Question

If the function f(x) = x^2 + 2 has the domain {0,3,6,9}, what is the range?

Answer 1

We need to evalute the domain given in the function in order to obtain the range

we have the next function

$f(x)=x^2+2$

{0,3,6,9}

we will substitute each value

$f(0)=0^2+2=2$$f(3)=3^2+2=9+2=11$$f(6)=6^2+2=36+2=38$$f(9)=9^2+2=81+2=83$

the range of the function for the domain given is {2,11,38,83}

As we can see the
