Chapter 14: Q. 17 (page 889)

In Problems 13鈥�32, use the accompanying graph ofy=f(x).

Findf(-8)andf(-4).

Short Answer

Expert verified

The answer isf(-8)=0.f(-4)=2.

Step by step solution

01

Step. 1 Given

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

02

Step. 2 Final answer

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

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