Answer
a) $f(-2)= -1.4$
b) $f(-6)= 1$
Work Step by Step
a) The graph shows that when $x= -2$, $y= -1.4$. Therefore:
\begin{equation}
\begin{aligned}
f(-2)&= -1.4.
\end{aligned}
\end{equation} b) The graph shows that when $y= 1$, $x= -6$. Therefore:
\begin{equation}
\begin{aligned}
f(-6) & =1.
\end{aligned}
\end{equation}
