Graph the function f(x) = (x + 1)(x – 5). use the drop-down menus to complete the steps needed to graph the function. identify the x-intercepts: (–1, 0) and (5, 0) find the midpoint between the intercepts: (2, 0) find the vertex: find the y-intercept:

Step-by-step explanation:

Here the function is,

The x intercept is the point where the graph intersects the x axis or the point where y or f(x) is 0.

So,

Hence the x-intercepts are

Their mid point will be,

The general vertex form of quadratic function or parabola is,

where (h, k) is the vertex.

Here,

Comparing this to the general form, the vertex is

The y intercept is the point where the graph intersects the y axis or the point where x is 0.

Putting x=0 in , we get

Therefore, the y intercept is
