Question

Answer is in red but i need the work done

Answer 1

The function given is

`f(x)=x^4-6x-8`

The value of the function when x equals to -5.

`f(-5)=(-5)^4-6(-5)-8`
`f(-5)=625+30-8`
`f(-5)=647.`

Thus the value of the function at x =-5 is 647.

Similarly the value of the function when x=2.

`f(2)=(2)^4-6(2)-8`
`f(2)=16-12-8`
`f(2)=4-8`
`f(2)=-4`

Thus the value of the function when x=2 is -4.
