Question

Given the functions: f(x) = 4x + 8 and g(x) = 2x − 3.

Make a table of values for each function to determine which value of x is closest to where g(x) begins to exceed f(x).
A) x = 4
B) x = 5
C) x = 6
D) x = 7

Answer 1

x=5

B

Explanation:

2^5-3= 32-3= 29

4(5)+8= 20+8= 28

Answer 2

Your answer is B

B) x+5

Explanation:

x = 5

f(x) = 4x + 8 = 4(5) + 8 = 28

g(x) = 2x − 3 = 25 − 3 = 29

A quantity increasing exponentially eventually exceeds a quantity increasing linearly.
