11. find all relative extrema for f(x) = 3x + 7x2 + x +5.
a) relative maximum (nearest tenth)
b) relative minimum (nearest tenth)
c) increasing (nearest tenth):
d) decreasing (nearest tenth):

Rel. Minimum- -0.3

Rel. Maximum - None

Increasing on: -0.3, infinity

Decreasing on: -Infinity, -0.3

Step-by-step explanation:

f(x) = 3x + 7x2 + x +5

To find the relative minimum, punch the equation into your graphing calculator and you should get -2/7 as your minimum. (Divide it for a decimal number)

There is no relative maximum because of this parent function type.

Increasing on: -2/7, infinity

And Decreasing on: -infinity, -2/7

so then what are you asking?

step-by-step explanation:

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
