Answer:
x-intercept (s):
For this case h (x) = 0
x2 - 2x - 8 = 0
(x-4) * (x + 2) = 0
x1 = 4
x2 = -2
y-intercept:
For this case x = 0
h (0) = (0)2 - 2 (0) - 8
h (0) = - 8
vertex:
We derive the equation:
h '(x) = x2 - 2x - 8
h (x) = 2x - 2
We match zero:
2x-2 = 0
x = 2/2
x = 1
We evaluate the function for x = 1
h (1) = (1)2 - 2 (1) - 8
h (1) = 1 - 2 - 8
h (1) = -9
The vertex is:
(1, -9)
axis of symmetry of the function:
x = 1

Hi there,
I used the Desmos graphing calculator to graph the point -3≥x-y and this is what i got
Your coordinate points will be (0,3) and (-3,0)
Hope this is correct :)
Have a great day
Step-by-step explanation:
1/4 of the book = 66 pages
1/2 of the book = 132 pages
3/4 of the book = 132 + 66 = 198 pages
