At which point does the graph y = x^3 - 8 cut the x-axis?

Answer and explanation

Correct answer: (2, 0)

Answer: option A, (2,0). Every point on the x-axis has y-coordinate zero. Therefore, to find where the graph meets the x-axis, put y=0 in y=x³−8. We obtain 0=x³−8, so x³=8. The real cube root of 8 is 2, giving the point (2,0). Substitution verifies it: 2³−8=8−8=0. Option B, (−2,0), is wrong because (−2)³−8=−8−8=−16, not zero. Option C, (0,8), is the y-intercept, obtained by setting x=0. Option D incorrectly uses the constant 8 as the x-coordinate without solving the equation. Remember: x-axis means y=0, while y-axis means x=0.
