Question
consider the following piece - wise - defined function.
f(x)=\begin{cases}-x + 6&\text{if }xleq - 2\\4x - 7&\text{if }x > - 2end{cases}
step 1 of 3: evaluate this function at (x=-2). express your answer as an integer or simplified fraction. if the function is undefined at the given value, indicate “undefined”.
answer
selecting a radio button will replace the entered answer value(s) with the radio button value. if the radio button is not selected, the entered answer is used.
f(-2)=squarequad\text{undefined}
Step1: Identify the relevant part of the function
Since $x=-2$ and the condition $x\leq - 2$ corresponds to $f(x)=-x + 6$, we use this part of the piece - wise function.
Step2: Substitute $x = - 2$ into the function
Substitute $x=-2$ into $f(x)=-x + 6$. So $f(-2)=-(-2)+6$.
Step3: Simplify the expression
$f(-2)=2 + 6=8$.
