Question

Which is the graph of f(x) = RootIndex 3 StartRoot x EndRoot?

On a coordinate plane, a cube root function goes through (negative 8, negative 2), has an inflection point at (0, 0), and goes through (8, 2).

On a coordinate plane, a cube root function goes through (negative 2, 8), has an inflection point at (0, 0), and goes through (2, negative 8).

On a coordinate plane, a cube root function goes through (negative 8, 2), has an inflection point at (0, 0), and goes through (8, negative 2).

Answer 1

The first one. Because ∛(-8) = -2, ∛(0) = 0 (inflection point), and ∛(8) = 2, so the cube-root graph passes through (-8,-2), (0,0), and (8,2).
