Yes, I believe so, it could be an exponential function.
the point of intersection on the graph are (3,-2)
For some base area B and height h, the volume of a pyramid is
... V = (1/3)Bh
For the same base area and height, the volume of a rectangular prism is
... V = Bh
You will note that the factor of 1/3 is missing, meaning that the volume of the prism is 3 times the volume of the same-dimensions pyramid.
The prism has a volume of 3×(8 cm³) = 24 cm³.
No, you can't. If the denominator is greater than the numerator, that fraction's absolute value is always less than 1. If the numerator is greater than the denominator, that fraction's absolute value is always more than 1. Therefore, for both of them to be equal to each other, you are saying that a fraction that is less than 1 is equal to the fraction more than one. However, you can have a fraction with a larger denominator actually be of greater value than the one with the larger numerator. For example, -(9/8) vs -(8/9). -(9/8) has a greater numerator, yet -(8/9) is greater than it, despite having a larger denominator. Of course, this case can be written off as having the negative factored in with either the numerator with denominator, so it is easier to remember the rule above without the negative mumbo jumbo.
