Question

6.
a. $f(-3) =$
b. $f(4) =$
c. $f(1) =$
d. $f(-1) =$
e. $f(0) =$

Explanation:

Step1: Locate x=-3 on the graph

Find the point on the line where $x=-3$, its y-value is $-2$.

Step2: Locate x=4 on the graph

Find the point on the line where $x=4$, its y-value is $4$.

Step3: Locate x=1 on the graph

Find the point on the line where $x=1$, its y-value is $1$.

Step4: Locate x=-1 on the graph

Find the open circle at $x=-1$, its y-value is $1$ (the closed circle is not at $x=-1$).

Step5: Locate x=0 on the graph

Find the point on the horizontal segment where $x=0$, its y-value is $1$.

Answer:

a. $f(-3) = -2$
b. $f(4) = 4$
c. $f(1) = 1$
d. $f(-1) = 1$
e. $f(0) = 1$
