You can put this solution on YOUR website!
f(x) = x%5E2+-+7x+%2B+10

f(0) means put 0 everywhere you had x, so we get f(0) = 0%5E2+-+7%280%29+%2B+10
--> f(0) = 10

f(5) means put 5 everywhere you had x, so we get f(5) = 5%5E2+-+7%285%29+%2B+10
--> f(5) = 25 - 35 + 10
--> f(5) = 0

f(-2) means put -2 everywhere you had x, so we get f(-2) = %28-2%29%5E2+-+7%28-2%29+%2B+10
--> f(-2) = 4 + 14 + 10
--> f(-2) = 28
