Explain how you would find the x-intercepts and y-intercept for quadratic
functions?
To find x-intercepts, let y = 0 and solve for x using factoring or
the quadratic formula.
----------------------------------
To fiind the y-intercept, let x = 0 and solve for y.
==================================================================
Are there situations where graph of quadratic functions have
only one x-intercept?
Yes, when the discriminant of the quadratic = 0
---------------------------------------------------
Situations where there are no x-intercepts?
Yes, when the discriminant of the quadratic is negative.
===================================================
