Linear, Exponential and Quadratic Functions Pre assessment

Two functions are shown below.

For what value of x will f(x) = g(x)?

f(x) = 20x – 6

g(x) = 2(3)^x

• x = 1

• x = 2

• x = 3

• x = 4

Two functions are shown below.

For what positive minimum value of x will f(x) exceed g(x)?

f(x) = x² - 5x + 6

g(x) = 2x + 8

• x = 3

• x = 5

• x = 7

• x = 8
