Module 4: Exponential & Logarithmic Functions

About This Assessment

This pre-assessment helps us understand what you already know about exponential and logarithmic functions before you begin the module. Your answers will not be graded - this is simply a baseline measurement.

Time: 5-10 minutes | Questions: 5 | Purpose: Baseline measurement

Question 1

Evaluate f(x) = 2^x when x = 3.

A. 6
B. 8
C. 9
D. 32

Question 2

Which function represents exponential growth rather than linear growth?

A. f(x) = 3x + 5
B. f(x) = x² + 1
C. f(x) = 3^x
D. f(x) = -2x + 7

Question 3

Evaluate log₂(8).

A. 2
B. 3
C. 4
D. 16

Question 4

If you invest $1000 at 5% annual interest compounded annually, which formula represents the amount A after t years?

A. A = 1000 + 5t
B. A = 1000(1.05)^t
C. A = 1000(0.95)^t
D. A = 1000 + 50t

Question 5
