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

Thank you; those are your four answer choices. Which one is correct? And what do the directions ask you to do?
anonymous
  • anonymous
select all of them that are true

at lease 2 have 2 be right
anonymous

at most 2 correct

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}.

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

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

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

f(0)=0

f(x)=[[x]]

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?

idk i just need to find out wat ones are true

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?

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?"

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 |dw:1449455578434:dw|
