domain of -2x^2=x-1 is ?
What solutions do you obtain? Are you aware of how to solve a quadratic equation ?
The domain is the set of x values. Is there any value of x that would cause the equation to be undefined?
Domain is used to refer to the valid inputs of a function, but we are given an equation. The only valid inputs to an equation are its solution set.
oops its suppose to say -2x^2+x-1
