Question

In Problems 13–32, use the accompanying graph of$y=f\left(x\right).$

Find$f(-8)andf(-4).$

Short answer

The answer is$$\begin{gathered} f(-8)=0. \\ f(-4)=2. \end{gathered}$$

Step-by-step solution

Step. 1 Given

We have to find the points on graph which intersect with the lines $x=-8andx=-4$respectively to find$f(-8)andf(-4)$.

Step. 2 Final answer

So, from analyzing the graph when $x=-8$the graph intersects the x-axis which means the y co-ordinate is 0. Therefore, $f(-8)=0$.

Similarly, when $x=-4$the graph touches it at the co-ordinate (-4,2) as mentioned in the graph itself. Therefore,$f(-4)=2$.
