Question

Evaluate the function for the given value of x.f(x)=n^4+10n^3+22n^2-15n-22 at n=-4

Answer 1

`f(n)=n^4+10n^3+22n^2-15n-22`

To evaluate the function, you have to replace the given value of n into the function, as follows:

`\begin{gathered} f(-4)=(-4)^4+10\cdot(-4)^3+22\cdot(-4)^2-15\cdot(-4)-22 \\ f(-4)=256+10\cdot(-64)+22\cdot16+60-22 \\ f(-4)=256-640+352+60-22 \\ f(-4)=6 \end{gathered}`
