Question

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

Answer 1

to find x-intercept,put y=0

Answer 2

\[y − 8 = x^2 − 6x\]

when y=0
\[0 = x^2 − 6x+8\]

quadratic

x=2 and x=4

Answer 3

Rearrange the equation to read y=x^2 -6x + 8. You will note that it factorable
(x-4)(x-2)=0
thus the zeroes occur at x=4 and x=2.
