Question

Help please?! Find any points of discontinuity for the rational function.
y=(x-8)/(x2+6x-7)

x = 1, x = 7
x = 8
x = 1, x = –7
x = –1, x = 7

Answer 1

y = (x-8)/(x+7)(x-1)
so function is not defined at x = 1 and x = -7 so these are the points of discontinuity.
3rd part is correct

Answer 2

so your saying the answer is the 3rd answer?
