Question

PLEASE HELP IM TRYING TO FINISH THIS BY NEXT MONDAY AND IVE BEEN STUCK ON THIS

Answer 1

Answer:

A. F(x) has 1 relative minimum and maximum.

Step-by-step explanation:

${ \bf{F(x) = 2 {x}^{3} - 2 {x}^{2} + 1 }}$

As x and F(x) tend to positive and negative infinity:

${ \sf{x→ \infin : f(x) = \infin}} \\ { \sf{x→ {}^{ - } \infin : f(x) → {}^{ - } \infin}}$

❎So, B and C are excluded.

Roots of the polynomial:

${ \sf{f(x) = 2 {x}^{3} - 2 {x}^{2} + 1}} \\ { \sf{f(x) = - 0.6 \: \: and \: \: 0.8}}$

❎, D is also excluded.

✔, A
