Question

Evaluate f(x) = 14/x2 when x=7

Answer 1

Answer: 2/7

Explanation:

Fill in all the x's with 7 because x=7

So it'll look something like this

14/7^2 and 7^2 is 49

So 14/49 then you simplify that and it is 2/7

Answer 2

Rewrite the question as 14/7*2 and you will get 4.
So f(4) is your answer.
