Question

f(x)={-3x,x<0}
{4,x=0
{x^2,x>0

Answer 1

Please include the instructions that came with this problem. Why keep helpers guessing?

Answer 2

f(4)=0
f(3)=9
f(2)=4
f(1)=-3

Answer 3

give the piecewise function

Answer 4

Thank you; those are your four answer choices. Which one is correct? And what do the directions ask you to do?

Answer 5

select all of them that are true

Answer 6

at lease 2 have 2 be right

Answer 7

at most 2 correct

Answer 8

What you have typed in is called a 'piecewise function,' because its definitions change as the variable x increases.

f(x)={-3x,x<0}
{4,x=0
{x^2,x>0

It'd be clearer were you to present this function as follows:

f(x) = {-3x for x<0; 4 for x=0; and x^2 for x>0}.

Answer 9

Please explain how you arrived at your tentative answers.

Answer 10

so f(1)=-3 is correct thats one of them

Answer 11

its over the computer

Answer 12

Looking at the original function definition, determine what value F(x) has if x = 0.

Answer 13

i have the notes i am just cant get it my teacher cant get it either

Answer 14

f(0)=0

Answer 15

Please explain how you decided the following: so f(1)=-3 is correct thats one of them

Answer 16

f(x)=[[x]]

Answer 17

that's the "greatest integer function." I don't see how that's related to the problem you've posted.

What kind of help do you need?

Answer 18

idk i just need to find out wat ones are true

Answer 19

The question is HOW?

The given function is f(x) = {-3x for x<0; 4 for x=0; and x^2 for x>0}.
Show me that you understand what this means. First, what is the value of f(x) if x = 0?

Answer 20

i cant miss anymore or i will fail

Answer 21

0

Answer 22

You are guessing at the answers, and that helps neither you nor me. It's vital that you UNDERSTAND how to approach problems and to solve them yourself.

Please answer my previous question:

"The given function is f(x) = {-3x for x<0; 4 for x=0; and x^2 for x>0}.
Show me that you understand what this means. First, what is the value of f(x) if x = 0?"

Answer 23

idk

Answer 24

This a sketch of the how the piecewise function might look if I did it right.

When X = 4, 3, 2 or 1, what is the corresponding Y value equal and does it match any of the choices?

f(4)=0
f(3)=9
f(2)=4
f(1)=-3
