hey can someone anser this for me caz i need helpppppp and i dont get it lol?

Question

ok and if u do then i will chhose urs as best anser. and thanks ..........



NOTES: domain and range using set notation

Domain is the set of all possible "x" values.
Range is the set of all possible "y" values.

EXAMPLE: use the function rule f(x)=2x+3.

1. Find the range if the domain is {0, 1, 5}.

2. Find the range if the domain is {-5, 0, 5}.

3. Find the range if the domain is {0, 1, 2}.

4. Find the range if the domain is {-8, 0, 8}.



and thats it lol

HEY! i need help

is the last one right

Answer 1

case 1: the range is: {3,5,13}
case 2: the range is:{-7,3,13}
case 3: the range is:{3,5,7}
case 4: the range is:{-13,3,19}
easy huh???

Answer 2

You will need to do 12 substitutions to solve these range problems. Take one of your domain values and replace it for the x in the function.

Example: I'm going to pick the first 0 value, and replace x with 0 in the f(x) function.
2(0)+3 = 0+3 = 3
So the domain is 0, and the range is 3.

Continue to do that substitution for all of your domain values and you will find all of your range values.

Hope this helped and good luck.

Answer 3

you might consider doing your own homework , as someday you might be called upon to prove your quotent or theorum...
