Question

Evaluate the function f when we have at the indicated values. Type your answer in simplified form with descending powers of our variable. When typing an exponent use the carrot key ^ by pressing shift and 6. For example, x squared can be typed x^2.Do not include any spaces between characters.f(x)=|x-1|-|x+1|f(-a)=Answerf(a+h)=Answer

Answer 1

Step 1:

Write the parent function

`f(x)\text =`

Step 2:

To find f(-a), substitute x = -a

`\begin{gathered} f(x)\text - \\ \textx \\ of\text = \end{gathered}`
`\begin{gathered} \text{Therefore} \\ f(-a)\text-a + 1 \\ f(-a)\text-(a - 1) \\ f(-a)=\text a - 1 \end{gathered}`

Step 3:

`\begin{gathered} f(x\textx - 1 \\ f(a\text \end{gathered}`
