Question

Which function is larger for x=4? Circle one. Explain your reasoning A: Y=2x B: Y=2^x

Answer 1

The function 2^x is larger for x = 4

Explanation:

• Step 1: Find value of y = 2x for x = 4.

⇒ y = 2x = 2 × 4 = 8

• Step 2: Find value of y = 2^x for x = 4

⇒ y = 2^x = 2^4 = 16

Function 2^x is larger.
