Ay I need help on dis question please

Step-by-step explanation:

f(x) = (x + 3)^(1/3)

We notice that f(x) is a strictly increasing function.

Hence,

Minimum value of f(x) is when x = -11,

f(x) = (-11 + 3)^(1/3) = -2.

Maximum value of f(x) is when x = 5,

f(x) = (5 + 3)^(1/3) = 2.

P.S. You can differentiate f(x) to show that it is an increasing function.

Step-by-step explanation:

use remainder theorem,synthetic division or long division

i use remainder theorem and synthetic division

f(-3)=-2(-3)³+(-3)²-4(-3)+1=54+9+12+1=76

by synthetic division

-3 | -2   1    -4     1

   |        6  -21   75

      -2   7  -25 |76

so remainder is 76
