Find the domain and the range of the relation shown on the graph to the right. Use the vertical line test to determine whether
the graph is the graph of a function.
Find the domain of the relation. Select the correct choice below and fill in the answer box to complete your choice.
O A. The domain of the relation is the single value { }
(Type an integer or simplified fraction.)
OB. The domain of the relation is the interval
(Type your answer in interval notation.)

(ANSWER QUICKLY)

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
