Question

I need help finding the X Intercept for y= -3x^2-6x-5

Answer 1

easy

Answer 2

Set the function equal to 0 and find the 2 values of X

Answer 3

it is (5,1)

Answer 4

That coordinate is not even on the X axis.

Answer 5

discriminant will tell you how many

Answer 6

Thank You. I was so focused on trying to find a solution for X if Y = 0, that I didn't even chart it out to see that the X axis is not applicable to the problem.

Answer 7

A picture can be invaluable. In this case, the discriminant let us know to stop looking before we got crazy.
