Question

What is the relative maximum and minimum of the function?

f(x) = 2x3 + x2 - 11

A. The relative maximum is at (–1.53, 8.3) and the relative minimum is at (1.2, –12.01).

B. The relative maximum is at (–1.53, 12.01) and the relative minimum is at (1.2, –8.3).

C. The relative maximum is at (–1.2, 8.3) and the relative minimum is at (1.53, –12.01).

D. The relative maximum is at (–1.2, 12.01) and the relative minimum is at (1.53, –8.3).

Answer 2

do you have a typo in the question ? the local min of
\[ 2x^3 +x^2 -11 \] occurs at x=0 and a local max at x= -1/3

these do not coincide with any of your choices
