Determine the vertex of (f)=-×^2+50×-456

And for the coordinate on y we can use the function like this:

Then the vertex would be

Step-by-step explanation:

For this problem we have the following function given:

That represent a quadratic function and the general form is given by:

For this problem a =-1 , b= 50 , c=-456 and we can find the corrdinate of the vertex in x with this formula:

And replacing we got:

And for the coordinate on y we can use the function like this:

Then the vertex would be

126.25

Step-by-step explanation:

1. 8.75 x 8 = 70

2. 8.75 + 2.50 = 11.25

3. 11.25 x 5 = 56.25

4 70+ 56.25= 126.25
