Answer:
4x² - 20x + 16
Step-by-step explanation:
Given
(4x - 4)(x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(x - 4) - 4(x - 4) ← distribute both parenthesis
= 4x² - 16x - 4x + 16 ← collect like terms
= 4x² - 20x + 16
Look at the picture.
The perimeter of the triangle:
Using translation concepts, the equation for the transformed function h(x) is given by:
h(x) = f(-x - 1).
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the effect of the two changes is given as follows:
- Reflection over the y-axis, hence h(x) = f(-x).
- Translation of one unit right, that is, x -> x - 1, hence h(x) = f(-x - 1).
