Which equation represents an exponential function?

• y = x² - 5x + 24

• g(x) = 4.3x + 9

• f(x) = 2(4)^x

• f(x) = 2(4)²

Which statements about f(x) = 3^x are true?

• The y-intercept is (0,3)

• It represents exponential growth because the growth factor is greater than 1

• The y-intercept is (0,1)

• It represents exponential decay because the decay factor is 1

• f(4) = 81
