Answer:
With
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:
We can begin the zeros or the values where the function is 0 like this:
And solving for x we got:
Now we can rewrite the expression like this:
And we can find the position for the vertex at x with this formula:
With
And replacing we got:
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.
Then we can find the intercept using the value of x=0 and replacing into the function we got:
So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
Triangle area = base*height)2
Here, area = 23*28/2=322
Area = x4 + 4x3 + 3x2 - 4x - 4
Length = x3 +5x2 + 8x + 4
Width = Area / Length.
Performing long division with polynomial.
x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1
Width = x-1
Answer: The last one is the one with the Median
Step-by-step explanation: Hope this helps ^^
Im not sure but i think the answer is about 266.6
