Question

F(5)=3|x+11|-4, find f(5)

Answer 1

f(5) = 44

Explanation:

Given

f(x) = 3 | x + 11 | - 4

To evaluate f(5) substitute x = 5 into f(x)

f(5) = 3 | 5 + 11 | - 4 = 3 | 16 | - 4 = (3 × 16) - 4 = 48 - 4 = 44

Answer 2

f(5) = 44

Explanation:

f(x) = 3|x+11| -4

let x =5

f(5) = 3|5+11| -4

= 3|16| -4

= 3*16 -4

= 48 -4

= 44
