Exponential Growth Functions

Question 7 • Common Core Algebra I - MA3109 A-IC

Which equation represents an exponential function that passes through the point (2, 36)?

Answer

f(x) = 4(3)x

f(x) = 4(x)3

f(x) = 6(3)x

f(x) = 6(x)3

An exponential function has the variable in the exponent. For choice A, f(2) = 4(3)² = 4 × 9 = 36, so it passes through (2, 36).
