Question

To help solve the trigonometric inequality sec(x/3)+4>2-sec(x/3) which two equations could you graph

A.y=sec(x/3) and y =-2.

b.y=sec(x/3) and y=-1.

C.y=sec(x/3) and y=1

D.y=sec(x/3) and y=2

Answer 1

b. y=sec(x/3) and y=-1

Explanation:

sec(x/3) + 4 > 2 − sec(x/3)

2 sec(x/3) > -2

sec(x/3) > -1

Graph y = sec(x/3) and y = -1.
