The transformed equation y = -(x - 2)^2 - 3 compared to the parent function involves translating the parent function to the right by 2 units, reflecting the function across the y-axis and translating the function 3 units down
<h3>How to compare the function to its parent function?</h3>
The equation of the transformed function is given as:
y = -(x - 2)^2 - 3
While the equation of the parent function is given as
y = x^2
Start by translating the parent function to the right by 2 units.
This is represented as:
(x, y) = (x - 2, y)
So, we have:
y = (x - 2)^2
Next, reflect the above function across the y-axis
This is represented as:
(x, y) = (-x, y)
So, we have:
y = -(x - 2)^2
Lastly, translate the above function 3 units down
This is represented as:
(x, y) = (x, y - 3)
So, we have:
y = -(x - 2)^2 - 3
Hence, the transformed equation y = -(x - 2)^2 - 3 compared to the parent function involves translating the parent function to the right by 2 units, reflecting the function across the y-axis and translating the function 3 units down

Answer:
$23.75
Step-by-step explanation:
Ok, first, To solve the problem, we need the amount of square feet of each kite.
To calculate area of triangles, you multiply base with height, then divide by two. (bh/2)
Jake's kite is 5.5 feet long, and 6 feet tall, so we plug this into the equation to get: (5.5 · 6)/2
we simplify to get 33/2 = 16.5 square feet.
Then to get the total cost, we multiply 16.5 with 2.50 to get $41.25, which is the cost of Jake's kite.
Now, we do the same with Rob's kite. (3.5*4)/2 = 14/2 = 7, then multiply by 2.5 to get 7 * 2.5 = $17.5, and that's the cost of Rob's kite.
To get the final answer, we subtract 41.25 to 17.5, which is $23.75
