The square root of a number would be the inverse of an exponent.
so let’s say you have 9 to the 2nd power, or 9^2, it would be 81, because 9 multiplied by itself 2 times (hence the exponent, second power) would be 81.
now, the square root of 9 would be the number that, multiplied by itself 2 times, would be equal to 9.
3 times 3 is equal to 9, and since 3 is being multiplied by itself two times to get 9, the square root of 9 is 3.
does this make sense now?
let me know if you need more help, and please mark me brainliest! (:

Answer:
Option C and D that is y= tan x and y= cot x
Step-by-step explanation:
The range is the values of y means the values that y can take in a function:
So, range of tan x and cot x are all real numbers.
Period of tan x is 
Period of cot x is
Option A and B that is secx and csc x are discarded
Answer:
x = 35
y = 100
Step-by-step explanation:
∠AEB and ∠DEC are vertical angles because they are opposite each other; they are also equal because of this. We can write an equation to model the situation:
∠AEB = ∠DEC
50° = x° + 15°
x = 35
∠AEB and ∠AED are supplementary because the form a line; this means they add up to 180°
∠AEB + ∠AED = 180°
50° + y + 30° = 180°
y + 80° = 180°
y = 100
