Question 387060: Question: for each function determine whether it is one-to-one; if it is one-to-one, find a formula for the inverse
f(x)=2x^2+3x-5
tried factoring first, and Im not sure about what one-to-one means, I believe its when its not a parabola.

Hi,
One-to-one function is A function for which every element of the range of the function
corresponds to exactly one element of the domain.
Graphically one can use the horizontal line test to check for one-to-one
f(x)=2x^2+3x-5 this function is not a one-to-one function
2 different values of x will result in the same y value.
