Question

Given the function f(x) = |x + 5| find f(-10) and f(6)

Answer 1

f(x) = |x + 5| find f(-10) and f(6)

Part 1

we have

$f\mleft(x\mright)=|x+5|$

Find f(-10)

that means -----> the value of f(x) for x=-10

substitute in the given function

$\begin{gathered} f(x)=|-10+5| \\ f(x)=|-5| \\ f(x)=5 \end{gathered}$

Part 2

Find f(6)

For x=6

$\begin{gathered} f(x)=|6+5| \\ f(x)=|11| \\ f(x)=11 \end{gathered}$
