The polynomial is of degree 4, so it has at most 4 real zeros. From the calculations, we found all 4 zeros as x = -3, -2, 1, and 3. Therefore f(x) = (x+3)(x+2)(x-1)(x-3).
For x>3, f(x)increases rapidly. Therefore there are no zeros for x>3. The statement that x=5 is an upper bound for the zeros of f(x) is true.
When there is no number between a grouping symbol and a + or - sign, by default you can multiply the contents in the group by 1 to get rid of the grouping symbols.
The volume of a cylinder is the amount of space that will fit inside it. You can use the formula for the volume of a cylinder to find that amount! In this tutorial, see how to use that formula and the radius and height of the cylinder to find the volume. Check it out!
