Question

Determine the range of the function f(x)=3x-9 when the domain is {-2, 0, 3}.



{-6, 0, 9}


{-15, -9, 0}


{3, 9, 18}


{-2, 0, 3}

Answer 1

Answer 2

The domain is the set of x values for the function f(x)=3x-9.

So, you have to crank out the y values for the function using the given x values.

To help you get started, I'll do the first one.

f(x)=3x-9

f(-2) = 3 * (-2) - 9
= -6 -9
= -15.

Answer 3

-15 is one of the three values of the range.

If x = 0, then f(0) = what? @Demi_xx

Answer 4

my answer is b yea?

Answer 5

{-15, -9, 0} is corrrect.
