Question

The exponential function g, represented in the table, can be written as g(x) = a•b^x

X G(x)
0 12
1 9

Complete the equation for g(x).
g(x) =

Answer 1

G(x) = 12 * [3/4]^x

Evaluating if x was 0, anything to the power of x equals 1, which multiplied by 12 gives twelve. Evaluating for x = 1, 3/4 to the power of 1 gives 3/4, which multiplied by 12 gives 9.
