<h3>
Answer:</h3>
B). y = (x -3)(x +1)(x -1)
<h3>
Step-by-step explanation:</h3>
The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).
Selection B is the only choice that has these three factors.

When x = a is a zero of a polynomial function, (x -a) is a factor.
Answer:
y=1/2x+2
Step-by-step explanation:
This means that it is 8x-28=15+x. We let x equal the number. You can solve for the equation.
A quadratic function is one of the form f(X)=ax^2+bx +c,where a,b and c are numbers with 'a' not equal to zero.
The graph of a quadratic function is a curve called a parabola. Parabola may open upward or downward and vary in 'width' or 'steepness' , but all have the basic "U" shape.
All parabolas are symmetric with respect to a line called the axis of symmetry. A parabola intersects its axis of symmetry at a point called the vertex of the parabola.
You know that the two points determine a line. This means that if you are given any two points in the plane,then there is one and only one line that contains both points.
