Question

For which would you draw a dashed boundary line and shade to the left?
Answer:
a. x<-4
b. x≤-4
c. x>-4
d. x≥-4

Answer 1

please tell me which one if its a b c d

Answer 2

it's either a or b because you're shading to the left. i think a dashed boundary line goes with the < and > symbols, but im not sure. i know an open circle goes with the < and > symbols. and a closed circle goes with the <= and >= symbols
