Question

What is the relative maximum and minimum of the function? f(x) = 2x^3 + 2x - 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 1

This function is always increasing, so it does not have min or max.

Answer 2

That is what I thought but it don't give me a choice for that

Answer 3

The derivative of it is \( 6x^2 +2 >0\)

Answer 4

None of the above.
