Question

I need help with someone explaining how to find the range of this! This course didn’t explain anything!

Answer 1

`(-infinity,3)`, D

Explanation:

3 if x is greater than or equal to 1 is nothing. That leaves us with
`h(x)=2x+1` if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is
`(-infinity,3)`, which is D.
