<h2>Answer:</h2>
In mathematics, a parent function is the simplest function of a family of functions preserving the definition or shapes of the entire family. If you are familiar with the basic characteristics of these simple graphs, this will help you to analyze the shapes of more complicated graphs. So the Linear parent function is the identity function:
and these are the characteristics:
- It's a straight line.
- The slope of this line is m = 1
- This line passes through the origin.
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The x- coordinate of the vertex is at the midpoint of the zeros.
Given
f(x) = (x - 4)(x + 2)
Find the zeros by letting f(x) = 0 , that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then
=
=
= 1
Substitute x = 1 into f(x) for corresponding y- coordinate
f(1) = (1 - 4)(1 + 2) = (- 3)(3) = - 9
Vertex = (1, - 9 )
