I only know that $$(-\infty,\infty)$$ is A

scarlettfarra2000 · Answer

wouldn't B be something like this? 
$$[1,\infty)?$$

legomyego180 · Answer

First off, what type of graph is this?

erak · Answer

yeah, A and B are correct. For C and D just look if the line crosses the x or y axis anywhere. It says to use the graph visually so I guess just take the given x values and find the y value

scarlettfarra2000 · Answer

@legomyego180 I'm not sure what graph this is

legomyego180 · Answer

f(x)=|x+2|+1

legomyego180 · Answer

Its the graph of an absolute value, which means that this is a piecewise function.

legomyego180 · Answer

Sorry, I was making this more complicated than it needed to be. Nvm.

scarlettfarra2000 · Answer

Okay I got every other one but D how would I find D? @legomyego180

scarlettfarra2000 · Answer

And E?

legomyego180 · Answer

What are the values of y where x=-4 and x=-2?

legomyego180 · Answer

Er x=2

atrineas · Answer

Yes B would be 
$$[\infty ,1)$$
D would be (0,3) because the line passes through the Y axis there 
C would be none because the line doesn't pass through the x axis at any point
E would be F(-4)=3 and F(2)=5 because f(x)=the value of Y when x is -4 or 2

scarlettfarra2000 · Answer

D isn't right
