Answer:

iii. (p - 7)(p - 3)

iv.(x - 8)(x + 4)

Step-by-step explanation:

iii. p² - 10p + 21

= p² - (7 + 3)p + 21

= p² -7p -3p + 21

= p(p - 7) - 3(p - 7)

= (p - 7)(p - 3)

iv. x² - 4x - 32

= x² - (8 - 4)x - 32

= x² - 8x + 4x - 32

= x(x - 8) + 4(x - 8)

= (x - 8)(x + 4)

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
