these divide by four each time. the fifth would be 224/4, which is 56. the sixth would be 56/4, which is 14.
Restrictions for f and g: denominators can't be equal to zero.
1
• For f(x) = —— :
x²
x² ≠ 0
x ≠ 0
So the domain of f is
Dom(f) = {x ∈ R: x ≠ 0}
Dom(f) = R*
or using the interval notation,
Dom(f) = ]–∞, 0[ ∪ ]0, +∞[ .
________
5
• For g(x) = —— :
x²
Since g(x) = 5 · f(x), the restrictions for g are the same:
x² ≠ 0
x ≠ 0
So the domain of g is also
Dom(g) = {x ∈ R: x ≠ 0}
Dom(g) = R*
or using the interval notation,
Dom(g) = ]–∞, 0[ ∪ ]0, +∞[.
I hope this helps. =)

To find the volume of a triangular pyramid, the formula is:
So we start by finding the area of the base, which is in the shape of a right triangle in this case.
The area of a right triangle is equal to 1/2 x base x height.
We use this area to find the volume.
The volume of the triangular pyramid is 30 cubic feet.
