## anonymous 5 years ago What is the domain of f(x)=2x-1/ x^2+2x-3

1. anonymous

it is $\frac{2x-1}{x^2+3x-3}$?

2. anonymous

no the bottom is x^2+2x-3

3. anonymous

if so, ignore the numerator and find the zeros of the denominator. $x^2+2x-3=0$ $(x-1)(x+3)=0$ $x=1$ or$x=-3$ so all real numbers except 1 and -3
