Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
f(x) = x^2 - 7x + 10
f(0) = 0^2 - 7(0) + 10 = 10
f(5) = 5^2 - 7(5) + 10 = 25 - 35 + 10 = 0
f(-2) = (-2)^2 - 7(-2) + 10 = 4 + 14 + 10 = 28

I have to evaluate this equation, but don't undersand it all please help me
f(x)=x^2-7x+10 [Substitute each value of x into the equation and solve]
.
(a)f(0) = = 0-0+10 =10
.
(b)f(5)= = 25-35+10 = 0
.
(c)f(-2)= = 4+14+10 = 28
