Question

Identify the type of function represented by f(x) 4 2^x

Answer 1

B bc the coefficient is greater than 1. if, for example it was 0.5 it would be a

Answer 2

f(x) = 4*2ˣ = 2ˣ⁺²

The answer is B because it is an exponential function since x is an exponent. Also, decay mean decreasing and growth means increasing. The function 2ˣ⁺² is "growing" as x gets bigger because the base is not a fraction.
