Question

What is the output of the following for x=-4? f(x)=3x^5+4x^3-x+11

Answer 1

f(x) = -3313

Explanation:

We are given the following function and we are to find its output when the value of x is -4:

`f(x)=3x^5+4x^3-x+11`

Substituting the given value of x in the above function to get:

`f ( -4 ) = 3 ( - 4 ) ^ 5 + 4 ( - 4 ) ^ 3 - ( - 4 ) + 1 1`

`f ( - 4 ) = ( - 3 0 7 2 ) + ( - 2 5 6 ) - ( - 4 ) + 1 1`

`f ( - 4 ) = - 3 3 1 3`

Answer 2

Answer: The output for
`x=-4` is -3313

Explanation:

The input values are the values of x, and the output values are the values of y.

Then, in this case, the input value is
`x=-4` and the output value for it can be obtained by substituting this input value into the function
`f(x)=3x^5+4x^3-x+11` and simplifying.

Therefore, the output value for
`x=-4` is:

`f(x)=3x^5+4x^3-x+11\\f(-4)=3(-4)^5+4(-4)^3-(-4)+11\\f(-4)=3(-1024)+4(-64)+4+11\\f(-4)=-3313`
