Question

Can you help me with this?? please explain

Answer 1

Hello!

We separate this into three sections

we are looking for a graph that has a line where x is greater than -3 and less than -2 while the circles not shaded since it does have the or equal to sign

The graphs that have this is the first and the third

Next we can look for the graph that has x greater than or equal to -2 and less than 3 with the one at -2 shaded but the one at 3 not

The graph that follows this is the third graph

The answer is the third one

Hope this helps!

Answer 2

The only graphs with the right y-values are A and C. Graph A is double-valued at x=3, so is incorrect.

The appropriate choice is
  Graph C
