Question 205923
 Q(x)=5x2-6x+3; find Q(1/2)
Q(1/2) = 5(1/2)^2 - 6(1/2) + 3
= (5/4) - 3 + 3
= 5/4
============================================

Determine the domain of the function.
P(x)=x^2-2x-10
     ---------
     5x^2+10x
------------------------
Factor to get:
P(x) = [x^2-2x-10)/[5x(x+2)]
---
Since the denominator cannot be zero,
x cannot be 0 and x cannot be -2
---
Domain: All Real Numbers except x = -2 and x = 0
