To write: The quadratic function in intercept form.
Answer to Problem 72E
The x- intercepts are 3 and
The y- intercept is
The vertex is
The axis of symmetry is
Explanation of Solution
Given Information: The quadratic function is
Calculation:
The intercept form of a quadratic function is given by,
Here, p, and q are the x- intercepts.
Therefore, the x- intercepts are 3 and
To find the y- intercept put
Therefore, the y- intercept is
The x-coordinate of the vertex of the parabola of the form
The x- coordinate of the parabola
The y -coordinate is,
Therefore, the vertex is
The axis of symmetry is given by the x coordinate of the vertex,
