**Henry**, Sunday, January 27, 2013 at 5:27pma. F(x) = (5x-2)/(x^2-5x+6)

F(x) = (5x-2)/(x-2)(x-3).

Any value of x that causes a zero

denominator is outside of the domain.

X = 2 and X = 3 will cause the denominator to be o. Therefore, they are outside of the domain.

Domain: All real values of X except 2, and 3.

b. Sqrt(5-2x).

Any value of X that causes the radical to go negative is outside the domain.

2x > 5.

X > 5/2

X > 2.5 is outside of domain.

Domain: X <= 2.5. Or 2.5 > X =2.5.
