Let f(x)=8x−6. What is the value of f(12)?

f(12) = 90

Step-by-step explanation:

This is more of a notation problem than anything else.

The x on the left means that the variable is x. That sounds weird I know, but it starts out this way.

f(variable) =  8*variable - 6

Where you see the word variable, you put the letter x and that gives you the question.

f(x) = 8*x - 6

That is math shorthand for whatever you see on the left, like an x or in this case 12, you put the value 12 in for x on the right. It will look like this.

f(12) = 8*12 - 6   Now it just becomes a calculator problem.

f(12) = 96 - 6

f(12) = 90

i would say c is the best answer, hope it's right!

good luck! =)
