Front

How do you determine if a function is growing or decaying?

Back

If the base of the exponential function is greater than 1, it is growing; if it is between 0 and 1, it is decaying.

Front

What does the coefficient in an exponential function represent?

Back

The coefficient represents the initial value of the function when x = 0.

Front

How do you find the composition of functions?

Back

To find the composition of functions f(g(x)), substitute g(x) into f(x).

Front

How do you find the y-intercept from a linear equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What is the difference between growth and decay in exponential functions?

Back

Growth occurs when the base is greater than 1, while decay occurs when the base is between 0 and 1.
