The function is given as:
At 9am, x = 9.
So, we have:
Evaluate the difference
Evaluate the exponent
Evaluate the sum
Approximate

<h3>The function transformation</h3>We have:
The parent function is:
So, the transformations applied to the parent function are:
- Vertical compression by a scale factor of 4
- Horizontal shift to the right by 3 units
- Vertical shift up by 2 units
The domain is the possible input values, and the range are the possible output values.
There are 24 hours in a day.
So, the domain is:
Domain = [0,23]
While the range is [2,)

Step-by-step explanation:
Given
3(x + 3)² - 81 = 0 ( add 81 to both sides )
3(x + 3)² = 81 ( divide both sides by 3 )
(x + 3)² = 27 ( take the square root of both sides )
x + 3 = ± = ± 3
( subtract 3 from both sides )
x = - 3 ± 3
x = - 3 - 3 or x = - 3 + 3
→ a
