Find the vertex of f(x) = 3(x-7)(x+5) Please show your work.

^^ I’ve been having a bit of trouble with this question :( although it’s simple quadratics is not my strong suit

The vertex is at (1, -108).

Step-by-step explanation:

We have the function:

And we want to find its vertex point.

Note that this is in factored form. Hence, our roots/zeros are x = 7 and x = -5.

Since a parabola is symmetric along its vertex, the x-coordinate of the vertex is halfway between the two zeros. Hence:

To find the y-coordinate, substitute this back into the function. Hence:

Therefore, our vertex is at (1, -108).

the answer is 3,600,000 cubic centimeters

step-by-step explanation:

first you have to convert all the units into centimeters

2 meters = 200 centimeters

1.5 meters = 150 centimeters

to find the volume of a rectangular prism you multiply all the sides

120 * 200 * 150 = 3,600,000

the answer is 3,600,000 cubic centimeters

hope this !
