Find the x-intercepts of the parabola with vertex (5,-4) and y-intercept (0,96). write your answer in this form: (x1,,y2). if necessary, round to the nearest hundredth.

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)

answer: 1 + 1 = 11
