Best ResponseYou've already chosen the best response.1\(\large\color{black}{ \displaystyle f(x)=7x5 }\) This function gives you the output \(f(x)\) for every value of \(x\) that you plug into the function. Here, I will give you an *example*. If I wanted to evaluate the function for *x=3*, then this is what I would do: \(\large\color{black}{ \displaystyle f(3)=7\cdot35 }\) \(\large\color{black}{ \displaystyle f(3)=215 }\) \(\large\color{black}{ \displaystyle f(3)=16 }\)

Best ResponseYou've already chosen the best response.1You need to evaluate the function for *x=2* (not x=3). That means thaty you need to plug *2* instead of *x* into the function f(x). (Just as I did with 3, above,  but this time with a "2")

Best ResponseYou've already chosen the best response.0Would the answer be 9? I did 7 x 25 which is 9

Best ResponseYou've already chosen the best response.1\(\large\color{black}{ \displaystyle f(2)=7\cdot25=145=9 }\)\ You are exactly right! Good job!
