You can put this solution on YOUR website!
f(x)=x^2-7x+10;find (a) f(0), (b) f(5), and (c) f(-2)
:
Substitute the value for x:
(a) f(0)
x = 0
f(0) = 0^2 - 7(0) + 10
f(0) = 0 - 0 + 10
f(0) = 10
:
(b) f(5)
x = 5
f(5) = 5^2 - 7(5) + 10
f(5) = 25 - 35 + 10
f(5) = 0
:
(c) f(-2)
x = -2
f(-2) = -2^2 - 7(-2) + 10
f(-2) = +4 -(-14) + 10
f(-2) = +4 + 14 + 10
f(-2) = +28

This isn't so hard. Can you do it now?
