Question

Given f (x) =|6x-9 |, evaluate 8
Is it - F(8)=18
F(8)=33
F(8)=39
F(8)=11?​

Answer 1

Answer: To evaluate f(x) = |6x - 9| at x = 8, we substitute x = 8 into the equation.

f(8) = |6(8) - 9|

= |48 - 9|

= |39|

The absolute value of 39 is 39. Therefore, f(8) = 39.

So the correct answer is:

F(8) = 39

Answer 2

f(8) = 39

Explanation:

the absolute value function always gives a positive value , that is

| - a | = | a | = a

to evaluate f(8) substitute x = 8 into f(x) , that is

f(8) = | 6(8) - 9 | = | 48 - 9 | = | 39 | = 39
