What are the differences between arithmetic and geometric sequences?

Arithmetic: Constant difference, linear growth | Geometric: Constant ratio, exponential growth

What are the differences between exponential growth and exponential decay?

Growth: b > 1, increasing function | Decay: 0 < b < 1, decreasing function

What are the differences between exponential and logarithmic functions?

Exponential: Rapid growth/decay, horizontal asymptote | Logarithmic: Slow growth, vertical asymptote

What are the differences between f−1(x)f^{-1}(x)f−1(x) and 1f(x)\frac{1}{f(x)}f(x)1​?

f−1(x)f^{-1}(x)f−1(x): Inverse function | 1f(x)\frac{1}{f(x)}f(x)1​: Reciprocal of the function

What are the differences between linear and logarithmic scales?

Linear: Equal intervals represent equal changes | Logarithmic: Equal intervals represent equal proportional changes

Compare and contrast composite functions and inverse functions.

Composite: Combining functions sequentially | Inverse: Undoing a function

Compare the domain and range of exponential and logarithmic functions.

Exponential: Domain: all reals, Range: positive reals | Logarithmic: Domain: positive reals, Range: all reals

Compare solving exponential and logarithmic equations.

Exponential: Isolate, take logarithm | Logarithmic: Isolate, convert to exponential

Compare graphing exponential and logarithmic functions.

Exponential: Horizontal asymptote, rapid growth/decay | Logarithmic: Vertical asymptote, slow growth

Compare the effect of base on exponential and logarithmic functions.

Exponential: Larger base = faster growth/decay | Logarithmic: Base influences steepness and position

What does the graph of an increasing exponential function tell us?

It indicates exponential growth, where the rate of increase accelerates over time.

What does the graph of a decreasing exponential function tell us?

It indicates exponential decay, where the rate of decrease slows down over time.

What does the graph of a logarithmic function tell us?

It shows a slow rate of increase, approaching a vertical asymptote.

How does the base of an exponential function affect the graph?

A larger base results in faster growth or decay.

How does the base of a logarithmic function affect the graph?

The base affects the steepness and position of the graph relative to the y-axis.

What does a semi-log plot of exponential data look like?

A straight line, indicating a constant rate of growth or decay on a logarithmic scale.

How can you determine if a graph represents an exponential function?

Look for rapid growth or decay and a horizontal asymptote.

How can you determine if a graph represents a logarithmic function?

Look for a slow rate of increase and a vertical asymptote.

What does the y-intercept of an exponential function represent?

The initial value of the function.

What does the x-intercept of a logarithmic function represent?

The value for which the argument of the logarithm is equal to 1.

What is an exponential function?

A function of the form f(x)=abxf(x) = ab^xf(x)=abx, where a and b are constants, and b > 0 and not equal to 1.

What is a logarithmic function?

A function of the form f(x)=log⁡b(x)f(x) = \log_b(x)f(x)=logb​(x), which is the inverse of an exponential function.

Define arithmetic sequence.

A sequence where each term differs by a constant amount (common difference).

Define geometric sequence.

A sequence where each term is multiplied by a constant amount (common ratio).

What is a composite function?

A function formed by combining two or more functions, where the output of one function becomes the input of another.

What are inverse functions?

Functions that 'undo' each other. If f(g(x))=xf(g(x)) = xf(g(x))=x and g(f(x))=xg(f(x)) = xg(f(x))=x, then f(x)f(x)f(x) and g(x)g(x)g(x) are inverses.

What is a semi-log plot?

A graph that uses a logarithmic scale on one axis and a linear scale on the other.

Define the common difference in an arithmetic sequence.

The constant amount added to each term to get the next term.

Define the common ratio in a geometric sequence.

The constant amount multiplied by each term to get the next term.

What is the initial value in an exponential function?

The value of the function when x = 0 (the 'a' in f(x)=abxf(x) = ab^xf(x)=abx).
