Question

how would I find the points for the piecewise function:
f(x)={2x+1 if x >=0
x if x<0

Answer 1

Well, if x>=0, plug x into 2x+1, if x<0, plug x into x.

Answer 2

Can you give me examples?

Answer 3

If x = -1, then you'd plug -1 into x. If x = 1, you'd plug it into 2x+1 to get 3.

Answer 4

how do I figure out what the y point is if I plug -1 into x since there is only x in the equation??

Answer 5

y=x, so it'd be -1...

Answer 6

gotcha. ty!
