Question

What is the output of the following functions for x=2 f(x)=2x^4-x^3+5x-9

Answer 1

The output of the input x = 2 is 25

To get the output, we simply will substitute the value of 2 into the equation

We will represent every x by 2

We have this as;

`\begin{gathered} f(2)=2(2)^4-2^3\text{ + 5(2) - 9} \\ =\text{ 32 - 8 + 10 - 9} \\ =\text{ 25} \end{gathered}`
