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
Plug x = 1 in the y:
y = 26
Plug 
= 1 in inverse of a function:
x = 26
Thus, the given equation represents a function and inverse of the function exist if x ≥ 6.

Okay, so first, lets determine whether or not these are equivalent, which will lead us to our answer.
8/12 < lets simplify this
8/4 = 2
12/4 = 3
8/12 = 2/3
10/25
10/5 = 2
25/5 = 5
10/25 = 2/5
2/5 ≠ 2/3
These ratios are not proportional.
Answer:
7
Step-by-step explanation:
126 g is what you originally had which=60% of whats left
you have to find out how many 10 wedges she can cut from the cheese that is left over
Work Shown:to find how much is left you have to multiply 126 by 60% remember when you multiply you have to move the decimal, and decimal is moved twice, so the answer would be 75.60 after you were done solving it and the number that is closest would be 70 so you would multiply 10 by 7=70 and the reason you pick that is because it is closer to 75.60.
So 7 is the answer.
28) ANSWER: x=5
Because 5*5=25.
29) ANSWER: x=4
3x^2=48
Divide both sides by 3.
x^2=16
x=4
Because 4*4=16.
