Let y = 2(x – 5)2 – 6.
Kazeer [188]

The given equation represents a function and inverse of the function exist if x ≥ 6.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

y = 2(x – 5)² – 6

Part A:

Using vertical line test, we can find the whether the graph is a function or not.

After drawing a graph for the given curve, and drawing a vertical line.

The vertical line touches only one point for the one input.

The given equation represents a function.

Part B:

Replace x → y and y → x

x = 2(y – 5)² – 6

2(y – 5)² = x + 6

\rm y^-^1 = \sqrt{\dfrac{x+6}{2}} +5

Plug x = 1 in the y:

y = 26

Plug  \rm y ^-^1 = 1 in inverse of a function:

x = 26

Thus, the given equation represents a function and inverse of the function exist if x ≥ 6.

Nutka1998 [239]
72 minutes.  First convert the height of the pool to inches by multiplying the height in feet by 12 which equals 36.  Next multiply that by 2 because the pool is draining at -1/2 inches per minute, not -1 inch per minute.
