for the function y=x^2 - 5x - 6
(a) find the vertex
(b) find the y-intercept
(c) find the x-intercepts
(leave your answers in simplified radical form or, where appropriate, round to the nearest hundredth.)

Listed below

Step-by-step explanation:

This is a cuadratic function excercise.

We know that cuadratic functions have the following formula:

The graphic of this function will give us a parabola, that can be graphed knowing four points: the two or less x-intercepts, the y-intercept, and the vertex (Xv;Yv).

A) The vertex

The vertex is a point on the graph, so we have to know it's value on the X axis and on the Y axis.

To know the value of Xv we can calculate it using the following formula:

We know that in this case:

So we supplant said values on the formula and we get:

To know the value of Yv, we suppland the value of Xv on the function's formula.

So we know now that

and

b) The y-intercept is the value of C on the function's formula. We know that c=-6, so

c) The x-intercepts can be resolved using the following formula:

This means that this formula can have two posisible solutions:

Or:

So that are the X-intercepts: x=6 and x=-1

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
