1.Find the domain of the function. Make sure answer is in interval notation.
g(x)=7x/x^24
2.Find the domain of the function. Make sure answer is in interval notation.
f(x)=5x square root of x2

1. g(x) = 7x/(x^24)
x^24 = 0
x^2 = 4
X = + 2.
Domain: 2 <X< 2.
2. F(x) = 5x*sqrt(x2).
2 <=X< +Infinity.

Correction:
1. 7x/(x^24) = 7x/(x+2)(x2).
When X = +2, the denominator = 0. Therefore, +2 are not in the domain.
Domain: All real values of X except +2.
