Dimetri says that a function that is made of terms where the variables is raised only to an odd power will be an odd function.Do
lana [24]

Here we want to study the relation between the exponents in a polynomial function and the "odd" property of functions.

We will see that Dimetri is correct.

-------------------------------

We start by defining an odd function as a function such that:

f(-x) = -f(x).

Now, let's see a simple function with only odd exponents.

f(x) = a*x  (the exponent is 1, so it is odd).

if we evaluate this in x = 1, we get:

f(1) = a

If we evaluate this in x = -1, we get:

f(-1) = a*-1 = -a

Then this is odd.

Now let's see a more general case and why Dimetri is correct.

For the rule of signs, when we multiply 2 negative numbers, the <u>product is positive.</u>

So always that we have an even exponent on a negative number, the outcome will be positive.

This does not happen for odd exponents, because we can't separate all the products in groups of 2, thus if we take the <u>odd exponent of a negative number, the outcome is negative</u>.

Then for functions with only odd exponents, the <u>outcome for evaluating the function in a given input is exactly the opposite of evaluating the same function with the opposite input</u>.

This means that the function is odd.

Again, note that this only happens if the function only has odd exponents.

A cone has a radius of 1 foot and a height of 2 feet. How many comes of Liquid would it take to fill a cylinder with a diameter
maks197457 [2]

find the volume of the cone:

1/3 pi r squared × h

1/3 pi (1) squared × 2

= 2/3 Pi (feet cubed)

find the volume of the cylinder:

pi r squared × h

(the radius is 1 foot because its half the diameter which is 2 feet)

pi (1) squared × 2

= 2 Pi (feet cubed)

2 Pi is÷ 2/3 Pi

= 3

therefore it will take 3 cones of liquid to fill a cylinder with a diameter of 2 and height of 2
