Question

find the relative minimum and relative maximum points for the graph of f(x)=2x^3-6x^2-48x+24

Answer 1

First, graph the function

Answer 2

i got (-2,80) as the relative maximum and (4,-136) as the relative minimum.

Answer 3

Yup thats correct :)

Answer 4

what about with this one, f(x)=-2x^3+6x^2+18x-18?

Answer 5

i got (3,32) as the relative minimum and (-1,-3) as the relative maximum

Answer 6

I don't think the y value for your maximum is correct, try that again

Answer 7

(3,36) and (-1,-28)?

Answer 8

yupp thats better :)
