Question

y=-x+4 if x<-1 y=2x+7 if x≥-1

Answer 1

I need help, whoever helps Ill give good answer

Answer 2

Can you elaborate? You haven't really stated a question. Just an equation for a function

Answer 3

Okay sorry it took so long to answer, it has the { sign before both of the equations

Answer 4

I imagine it looks something like this:

y = {-x+4 if x<-1
{2x+7 if x≥-1

But that just defines the function. Do you want to graph it or something?

Answer 5

Yes I need to find x

Answer 6

This is what the function looks like. They don't really overlap, since it looks like they are piecewise. I'm still not sure what you're being asked to find..
