y%28x%29=x%5E2%2B2x-15
Replace x with the value and solve for y.

y%28-4%29=%28-4%29%5E2%2B2%28-4%29-15
y%28-4%29=16-8-15
y%28-4%29=-7

y%28-3%29=%28-3%29%5E2%2B2%28-3%29-15
y%28-3%29=9-6-15
y%28-3%29=-12

y%28-2%29=%28-2%29%5E2%2B2%28-2%29-15
y%28-2%29=4-4-15
y%28-2%29=-15

y%28-1%29=%28-1%29%5E2%2B2%28-1%29-15
y%28-1%29=1-2-15
y%28-1%29=-16

y%280%29=%280%29%5E2%2B2%280%29-15
y%280%29=0%2B0-15
y%280%29=-15

y%281%29=%281%29%5E2%2B2%281%29-15
y%281%29=1%2B2-15
y%281%29=-12
