Question

What is the range of the function f(x) = 12 − 3x for the domain {-4, -2, 0, 2, 4}?

Answer 1

{24, 18, 12, 6, 20}



{6, 12, 18, 24, 30}



{-12, -6, 0, 6, 12}



{0, 6, 12, 18, 24}

Answer 2

will medal

Answer 3

Hey.
So you have a collection of `inputs` for this function:
{-4, -2, 0, 2, 4}

They want to know what `outputs` those will produce when you plug them into the function.

Answer 4

\[\large\rm f(\color{orangered}{x}) = 12 − 3(\color{orangered}{x})\]Let's plug in our first value from the domain set,\[\large\rm f(\color{orangered}{-4}) = 12 − 3(\color{orangered}{-4})\]So we've plugged in our first input,
what is the output?
Simplify.

Answer 5

my question says

Answer 6

What is the range of the function f(x) = 12 − 3x for the domain {-4, -2, 0, 2, 4}?


{24, 18, 12, 6, 20}



{6, 12, 18, 24, 30}



{-12, -6, 0, 6, 12}



{0, 6, 12, 18, 24}

Answer 7

thats it nothing else

Answer 8

I know what your question says. You don't need to post it again.
I'm asking you a very simple question to lead you to the correct answer.
I'm not just going to give it to you.

Answer 9

i got 20 from the formula

Answer 10

\[\large\rm f(\color{orangered}{-4}) = 12 − 3(\color{orangered}{-4})\]-3 times -4 gives us +12\[\large\rm f(\color{orangered}{-4}) = 12+12\]\[\large\rm f(\color{orangered}{-4}) = 24\]

Plugging our first value from the domain into the function,
gives us our first range value.

{ 24, , , , }

We don't know the others just yet, but we know that 24 is in that group.
It's looking like it's probably A,
but you should try another number just to make sure.\[\large\rm f(\color{orangered}{-2}) = 12 − 3(\color{orangered}{-2})\]\[\large\rm f(\color{orangered}{-2}) = ?\]
