f%28x%29=7x%2B7, for WHICH given values?
This is a line. Steep and positive slope, with point (0,7) included.

Pick the point you need.

f%28x%29=x%5E2%2B6x-8, is already "simplified". You could, if you want, change its form so to be able to read its vertex. (Otherwise, not factorable, this trinomial).

x%5E2%2B6x%2B9-9-8
x%5E2%2B6x%2B9-17
f%28x%29=%28x%2B3%29%5E2-17
