Question

Evaluate f (x) =2x-8 over the domain {0, 1, 3, 8} What is the range of f (x) ?

Answer 1

Answer:

{-8,-6.-2,8}

Step-by-step explanation:

we have

$f(x)=2x-8$

Evaluate f(x) for different values of x

For $x=0$ -----> $f(0)=2(0)-8=-8$

For $x=1$ -----> $f(1)=2(1)-8=-6$

For $x=3$ -----> $f(3)=2(3)-8=-2$

For $x=8$ -----> $f(8)=2(8)-8=8$

therefore

The range is equal to

{-8,-6.-2,8}
