Question

For f(x) = –2x + 7, find f(2).

Answer 1

I think its 3

Answer 2

good , you're right

Answer 3

it doesn't look like you are asking for a derivative so plug in a 2 to where you see x's
-2(2) + 7 = 3

Answer 4

\[\large{f(x)=-2x+7}\]
\[\large{f(2) = -2(2)+7=-4+7 =\color{blue}{3}}\]

Answer 5

Thank you both

Answer 6

You're welcome :)
