Question

Which of the following sets would have a graph with an open circle on 5 and a ray pointing left on the number line?
A.) {x | x R, x ≤ 5}
B.) {x | x R, x > 5}
A.) {x | x R, x < 5}

Answer 1

A.) {x | x R, x ≤ 5} 

This can not have open circle because of the ≤ sign


B.) {x | x R, x > 5} 

This will have an open circle at 5 but the arrow with point to the right because x > 5



C.) {x | x R, x < 5}

This is the one that will have a graph with an open circle on 5 and a ray pointing left on the number line because x < 5 

Answer 2

Answer:

Step-by-step explanation:

A.) {x | x R, x ≤ 5}

This can not have open circle because of the ≤ sign

B.) {x | x R, x > 5}

This will have an open circle at 5 but the arrow with point to the right because x > 5

C.) {x | x R, x < 5}

This is the one that will have a graph with an open circle on 5 and a ray pointing left on the number line because x < 5
