Answer:
The x-intercepts are
(x1,y1)=(4,0)
(x2,y2)=(6,0)
Step-by-step explanation:
we know that
The equation of the given parabola is

we have
the vertex is the point (5,-4)
substitute

The y-intercept is the point (0,96)
substitute and solve for a



The equation of the vertical parabola is equal to

Find the x-intercepts
Remember that
The x-intercepts are the values of x when the value of y is equal to zero
For y=0

Simplify

Rewrite

square root both sides




therefore
The x-intercepts are
(x1,y1)=(4,0)
(x2,y2)=(6,0)
