Answer:
Option A. [tex]\{-12.8,-6.4,0,6.4,12.8\}[/tex]
Step-by-step explanation:
we have
[tex]f(x)=3.2x[/tex]
we know that
To find the range, substitute each value of x of the domain and find the value of f(x)
so
For [tex]x=-4[/tex] -----> [tex]f(-4)=3.2(-4)=-12.8[/tex]
For [tex]x=-2[/tex] -----> [tex]f(-2)=3.2(-2)=-6.4[/tex]
For [tex]x=0[/tex] -----> [tex]f(0)=3.2(0)=0[/tex]
For [tex]x=2[/tex] -----> [tex]f(2)=3.2(2)=6.4[/tex]
For [tex]x=4[/tex] -----> [tex]f(4)=3.2(-4)=12.8[/tex]
therefore
The range is [tex]\{-12.8,-6.4,0,6.4,12.8\}[/tex]
