Question

If
f(x) = x2 + 2x − 3,
what is
f(7)?

Answer 1

f(7)=60

Explanation:

Replace the x in the equation with 7. If you use GEMDAS properly, you should arrive at the correct answer.

Answer 2

66

Explanation:

`f(x)=x^(2)+2x-3\\f(7)=7^(2)+2(7)-3\\f(7)=49+2(7)-3\\f(7)=49+14+3\\f(7)=63+3\\f(7)=66`
