To perform these various functions we need to simply substitute the (x) varaiable with the specified value or function of (x).
So...
f%28x%29=x%5E2-7%2B10
Substitute variable...
f%280%29=0%5E2-7%2B10
f%280%29=-7%2B10
f%280%29=3
Next...
f%285%29=5%5E2-7%2B10
f%285%29=25-7%2B10
f%285%29=18%2B10
f%285%29=28
And...
f%28-2%29=%28-2%29%5E2-7%2B10
f%28-2%29=4-7%2B10
f%28-2%29=-3%2B10
f%28-2%29=7
I hope this helps!
Good Luck!
