Answer:

Step-by-step explanation:
For example, we'll use this quadratic equation.

To understand how to plug it into the formula we need to know what each term represents.

So the equation above would be put into the formula like this.

Then we would solve

Now, the equation will branch off into one that solves when addition and one when subtraction.

So x={-3, -2} (-3 and -2)
Answer: 6
Step-byStep:
[(18- 8) x 3) + (4+3) x 6] divided by 12
step 1- start with the stuff in the parentheses
[(10 x 3) + (7 x 6)] divided by 12
step 2- simplify things in parentheses
[30 + 42] divided by 12
step 3- simplify even more
[72] divided by 12
step 4- remove brackets, and simply even further
72 divided by 12 = 6
Hope this helps
Answer:
The inverse of the function is ![f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx-16%7D%7B8%7D%7D)
Step-by-step explanation:
Inverse of a function:
Suppose we have a function y = g(x). To find the inverse, we exchange the values of x and y, and then isolate y.
In this question:

Exchanging x and y:



![y = \sqrt[3]{\frac{x-16}{8}}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx-16%7D%7B8%7D%7D)
The inverse of the function is ![f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx-16%7D%7B8%7D%7D)
310-85=225
225/25=9
