can someone correct this for me please.

Directions: Evaluate each function for the value specified.

f (x)=x^2+7c+10, f (-2)

so then this is what i did:

f(-2)=-2^2-7(-2)+10
= 4+14+10
= 28

so then that means that f(-2) = 28

sorry the formula should read. f(x)=x^2+7x+10 i need to find for f(-2)

(-2)=-2^2-7(-2)+10
= 4+14+10
= 28
If that is x^2+7x+10 then
-2^2+7(-2)+10=
4-14+10
??
