Formula for gravitational force?

F=G∗m1∗m2r2F = G * \frac{m_1 * m_2}{r^2}F=G∗r2m1​∗m2​​

Formula for electromagnetic force?

F=ke∗q1∗q2r2F = k_e * \frac{q_1 * q_2}{r^2}F=ke​∗r2q1​∗q2​​

Volume of a cylinder?

V=πr2hV = \pi r^2 hV=πr2h

Volume of a cone?

V=13πr2hV = \frac{1}{3} \pi r^2 hV=31​πr2h

How to shift a function f(x)f(x)f(x) horizontally by hhh units?

f(x−h)f(x-h)f(x−h). Right if h>0h > 0h>0, left if h<0h < 0h<0.

How to shift a function f(x)f(x)f(x) vertically by kkk units?

f(x)+kf(x) + kf(x)+k. Up if k>0k > 0k>0, down if k<0k < 0k<0.

How to vertically stretch/compress a function f(x)f(x)f(x) by a factor of aaa?

a∗f(x)a * f(x)a∗f(x). Stretch if ∣a∣>1|a| > 1∣a∣>1, compress if 0<∣a∣<10 < |a| < 10<∣a∣<1.

How to reflect a function f(x)f(x)f(x) across the x-axis?

−f(x)-f(x)−f(x)

How to reflect a function f(x)f(x)f(x) across the y-axis?

f(−x)f(-x)f(−x)

General form of a rational function?

f(x)=p(x)q(x)f(x) = \frac{p(x)}{q(x)}f(x)=q(x)p(x)​, where p(x) and q(x) are polynomials.

Difference between linear and polynomial models?

Linear: Straight line, constant rate of change | Polynomial: Curve, changing rate of change

Difference between polynomial and rational functions?

Polynomial: Can be written as a sum of terms with non-negative integer exponents. | Rational: Written as a ratio of two polynomials, may have asymptotes.

Difference between shifts and stretches of functions?

Shifts: Translate the graph without changing its shape. | Stretches: Change the shape by compressing or expanding the graph.

Difference between direct and inverse proportionality?

Direct: As one quantity increases, the other increases. | Inverse: As one quantity increases, the other decreases.

Difference between domain and range?

Domain: Set of possible input values (x). | Range: Set of possible output values (y).

Difference between continuous and piecewise functions?

Continuous: A single function defined over its entire domain without any breaks. | Piecewise: Defined by different functions over different intervals of its domain.

Difference between a vertical stretch and a horizontal compression?

Vertical Stretch: Multiplies the y-values by a factor, making the graph taller. | Horizontal Compression: Divides the x-values by a factor, making the graph narrower.

Difference between a vertical shift and a horizontal shift?

Vertical Shift: Moves the graph up or down by adding or subtracting a constant. | Horizontal Shift: Moves the graph left or right by adding or subtracting a constant from the x-value.

Difference between linear regression and polynomial regression?

Linear Regression: Finds the best-fitting straight line for the data. | Polynomial Regression: Finds the best-fitting polynomial curve for the data.

Difference between assumptions and restrictions in function modeling?

Assumptions: Simplifications made about the real-world scenario to create a tractable model. | Restrictions: Constraints on the domain or range of the function based on the real-world context.

Define a function model.

A mathematical representation of a real-world situation using a function.

What is a piecewise-defined function?

A function defined by multiple sub-functions, each applying to a certain interval of the main function's domain.

Define a rational function.

A function that can be defined as a quotient of two polynomial functions, i.e., f(x)=p(x)q(x)f(x) = \frac{p(x)}{q(x)}f(x)=q(x)p(x)​, where p(x) and q(x) are polynomials.

What does 'inversely proportional' mean?

A relationship where one quantity decreases as another increases, often modeled by a rational function.

Define domain in the context of function models.

The set of all possible input values (x-values) for which the function is defined and makes sense in the real-world context.

Define range in the context of function models.

The set of all possible output values (y-values) that the function can produce, considering the real-world context.

What is a parent function?

The simplest form of a function family, used as a basis for transformations. Examples: y=x2y = x^2y=x2, y=x3y = x^3y=x3, y=xy = \sqrt{x}y=x​.

Define a transformation of a function.

A change made to a parent function to fit a given data set, including shifts, stretches, compressions, and reflections.

What is linear regression?

A statistical method used to find the best-fitting linear relationship between two variables in a data set.

What is a rate of change in function modeling?

A measure of how one quantity changes with respect to another, often representing the slope of a function or its derivative.
