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:
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
