DAY 1 - ALG2 Exponential Functions Review

Front

In an exponential function, what does the 'a' represent?

Back

Y-INTERCEPT

Front

What is the common ratio in y=4(2)^x?

Back

2

Front

Describe the equation y = 100 * 2^x.

Back

It starts with 100 and is doubling.

Front

What type of pattern do exponential functions have?

Back

Multiplies by the same number every time.

Front

Which of the following is an exponential function? y = x^2, f(x) = 3x^3, y = x^3, f(x) = 3^x

Back

f(x) = 3^x.

Front

What is the general form of an exponential function?

Back

y = a * b^x, where a is the initial value and b is the base.

Front

What does the base 'b' in an exponential function indicate?

Back

The factor by which the function grows or decays.

Front

If b > 1 in an exponential function, what type of growth occurs?

Back

Exponential growth.

Front

If 0 < b < 1 in an exponential function, what type of decay occurs?

Back

Exponential decay.

Front

What is the y-intercept of the function y = 5 * 3^x?

Back

5.
