To find out the vertex we use formula
From the given f(x), the value of a=1, b=-8 and c=-9
Plug in the values in the formula

plug in 4 for x in f(x)
The value of y is -25
The vertex is (4,-25)
Answer:
The volume of a cone is given by the equation:
where
r is the radius of the cone
h is its height
We have several examples of cones in real life: for instance, the cone of an ice-cream, it has a conic shape.
The volume of a prism instead is given by:
where:
l is the length of the base
w is the width of the base
h is the height of the prism
Again, we have several examples of prisms in daily life: for example, boxes have usually the form of a prism, so it can be useful to know their size in order to calculate their volume.
