Question 474254: I need help with labeling x and y intercepts and/or vertex and label each axis of coordinate plane

Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

Check the discriminant, (

), If less than zero, the graph does not intersect the

and therefore has no

intercepts. If not less than zero, solve the quadratic equation for the two

values of the intercepts.

Where your function is in the form

, obtain the

-coordinate of the vertex from

. Obtain the

-coordinate of the vertex by evaluating the function at

The

-intercept of

(from setting

)

My calculator said it, I believe it, that settles it
