Question

What are the x-intercept(s) of the graph of y − 8 = x2 − 6x?

Answer 1

a. (−2, 0) and (4, 0)
b. (2, 0) and (−4, 0)
c. (2, 0) and (4, 0)
d. (−2, 0) and (−4, 0)

Answer 2

It's B right?

Answer 3

just substitute the y for 0, then you have when y=0
0 - 8 = x^2 -6x

Answer 4

then you have
0 = x^2 -6x + 8, do you know how to solve this

Answer 5

and b is not right

Answer 6

I don't know how to solve it

Answer 7

0 = (x-2)(x-4) (when you multiply this you will get same equation x^2-6x+8)
therefore you have
x-2 = 0 and x - 4 = 0
x=2 and x=4, so the values would be (2,0) and (4,0)

Answer 8

Thanks!
