Answer: 4π/15, 4π/3 and 28π/15 (in radians)
Step-by-step explanation:

Recall that 


= 
This implies that




Therefore the values of
between 0 and 2π are 48, 240 and 336. (All in degrees)
48 degrees= 4π/15 rad
240 degrees =4π/3 rad
336 degrees = 28π/15 rad
Answer:
No
Step-by-step explanation:
No, it's not a function as it fails the vertical line test
Answer:
2/3 is the correct answer so C. Hope this helps you. :)
Step-by-step explanation:
1/4 more................................................

We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict
, or
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is
.
