Question

20 If f(x) = 15x + 4, find f(x) when x = 2.
A 90
B 21
C 34
D 25

Answer 1

C 34

Explanation:

f(x) = 15x + 4 x = 2

f(x) = 15(2) + 4

f(x) = 30 + 4

f(x) = 34

Answer 2

Your answer is C. 34

Explanation:

Solve f(x) = 15x + 4 where x = 2

f(x) = 15x + 4

Substitute:

f(2) = 15(2) + 4

Multiply:

f(2) = 30 + 4

f(2)= 34

Your answer is C. 34
