Graph the function f(x) = (x + 1)(x – 5). Use the drop-down menus to complete the steps needed to graph the function
Effectus [21]

Answer:

0 = (x+1)(x-5)

x= -1 , x= 5

f(x) = x^2 -4x -5

V_x = -\frac{b}{2a}

With a = 1, b=-4 , c=-5

V_x = -\frac{-4}{2*1}= 2

f(2) = 2^2 -4*2 -5 = -9

f(0) = 0^2 -4*0 -5=-5

So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.

Step-by-step explanation:

For this case we know the following function:

f(x) = (x+1)(x-5)

We can begin the zeros or the values where the function is 0 like this:

0 = (x+1)(x-5)

And solving for x we got:

x= -1 , x= 5

Now we can rewrite the expression like this:

f(x) = x^2 -4x -5

And we can find the position for the vertex at x with this formula:

V_x = -\frac{b}{2a}

With a = 1, b=-4 , c=-5

And replacing we got:

V_x = -\frac{-4}{2*1}= 2

And then with the coordinate of x for the vertex we can find the coordinate of y replacing the value of x obtained for the vertex.

f(2) = 2^2 -4*2 -5 = -9

Then we can find the intercept using the value of x=0 and replacing into the function we got:

f(0) = 0^2 -4*0 -5=-5

So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
