Question

W(Click on graph to enlargeEvaluare f(o), and solve for f(x) = -1. If part b has more than one answer, input the larger number in the second field. Otherwise leave the second field blank.(a) f(0) = 4(b) f() = -1 f( 2) = -1

Answer 1

Question:

Solution:

According to the graph, the point (x,y) = (x,f(x)) =(0,4) belongs to the graph of the given function. Thus,

$f(0)=\text{ 4}$

On the other hand, notice that the points (x,f(x))=(x,-1), has two possible values for x:

$(x,-1)=(-2,-1)$

and

$(x,-1)=(2,-1)$

so that, we can conclude that the correct answers are:

$f(0)=\text{ 4}$

$f(2)=-1$
