Answer:
To determine the inverse of function f, change f(x) to y, switch x and y, and solve for y.

Step-by-step explanation:
f(x) = ![\sqrt[3]{8x} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%20%2B4)
Change f(x) to y: y = ![\sqrt[3]{8x} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%20%2B4)
Switch x and y: x = ![\sqrt[3]{8y} +4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D%20%2B4)
Solving for y: x - 4 = ![\sqrt[3]{8y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D)
(x-4)^3 = 8y
y = 

Therefore: inverse of function f =

Answer:
21 mails
Step-by-step explanation:
Let there are x no of texts and y no of emails.
Condition 1,
x+y = 20 ...(1)
Condition,
x=2y-1 ...(2)
Put the value of x from equation (2) in (1). So,
(2y-1)+y = 20
Taking like terms together,
2y-y=20+1
y=21
So, Devin sent 21 mails,.
Answer: 
Step-by-step explanation:
In the given picture, a parallelogram PQRS is given with angle 101°.
In a parallelogram opposite angles are equal.
Since, y is opposite to 101°.
Therefore y=101°
Also, the sum of the adjacent angles of a parallelogram is 180°
