Question

trying to find the x-intercepts of y=-(x-1)^3 -1

Answer 1

To find x-intercepts, set y = 0.

-(x-1)^3 - 1 = 0

Add 1 to both sides, you get

-(x-1)^3 = 1

Divide both sides by -1, you get

(x - 1)^3 = -1

What number cubed is -1? Answer is -1, becuase (-1)^3 = -1

so set x - 1 = -1

x = 0


Therefore, x = 0 is the ONLY x-intercept.

Answer 2

wow. For some reason I don't know why I could not set that up correctly. Thank you
