You can put this solution on YOUR website!
I'm going to assume that your function is f%28x%29+=+x%5E2%2B7x%2B10, because you didn't specify the sign in front of the 7x term.

To evaluate f(a) given f(x), you simply substitute a for x everywhere it occurs in the function and do the required arithmetic.

f%28x%29+=+x%5E2%2B7x%2B10, then f%280%29=%280%29%5E2%2B7%280%29%2B10=10.

I'm assuming that you know how to do arithmetic, so I'm going to leave the other two problems in your capable hands.
