Question

Given f(x) = 7x-2, what is the value of f(2)?

Answer 1

Answer:

f(2)=12

Step-by-step explanation:

f(x)=7x-2

Plug 2 into the equation, since it says "f(2)".

f(x)=7(2)-2

f(x)=14-2

f(x)=12, done!

Answer 2

Answer: 12

Step-by-step explanation: f(x) = 7x - 2 means that if we put an x into our function, a 7x -2 comes out.

So if we want to find f(2), that means we are putting a 2 into our function which means that a 7(2) - 2 comes out which simplifies

to 14 - 2 or 12. So f(2) = 12.
