The y-intercept is (0, 4).

To have the calculator find the x-intercepts (also called a zeros), use the CALC zero feature. You will need to answer three questions during this process. To set the Left Bound, enter any value of x near but a little to the left of the x-intercept. The Right Bound can be any value of x near but a little to the right of the x-intercept. For the guess, use a value of x that is close to the intercept itself.
