Question

f(x)=3x^2-3x, f (0)=, f (-1)=, f (2)=

Answer 1

plug, then chug.

Answer 2

what you mean plug than chug

Answer 3

Replace x with 0 and evaluate the function. Then do the same thing for -1 and 2. If you are sufficiently skilled in math to be evaluating powers (\(x^2\)) you should be sufficiently skilled in substituting values for a variable.

Did you have a specific question on how to arrive at an answer here?

Answer 4

Yes I have never done algebra this is my first year in algebra thats y I said how do you plug and chug

Answer 5

f(0) means take 0 and replace x with it. Then evaluate the function to find the result.

Answer 6

\[3(0)^2-3(0) = 3*0 - 3*0 = 0-0 = 0\]

Answer 7

Now do the same thing for -1 and 2.

Answer 8

ok so I use the 0 with the -1 and 2

Answer 9

No. You use the function with -1 and 2.

Answer 10

I am so sry I am still confused, I guess I just skip over it

Answer 11

No, don't skip over it. Figure out what is confusing to you. Is English your native language, cause it's not clear to me which part of my explanation doesn't make sense.

\[f(x) = 3x^2-3x\]

Now if I told you that x = 0 what would you do to find f(x) ?

Answer 12

will the answer be 0,3,6

Answer 13

Close.. Should be 0, 6, and 6.

Answer 14

Yea i didn't do that f(1) right

Answer 15

it's f(-1)

Answer 16

right

Answer 17

At least according to what you wrote initially.

Answer 18

Thanks so much I think I got it can I be a fan

Answer 19

So..
\[f(-1) = 3(-1)^2 - 3(-1)\]

Answer 20

Of course!

Answer 21

Thanks so much
