Which of the following is an odd function?
f(x) = 3x2 + x
f(x) = 4x3 + 7
f(x) = 5x2 + 9
f(x) = 6x3 + 2x

D)

Step-by-step explanation:

If it is an odd function, then f(-x) = -f(x)

If we plug in x = -x in f(x), we will get -f(x).

Now we have to check the given functions.

Let's check the function one by one.

f(x) =

Now plug in x = -x in the above function.

f(-x) =

Here f(-x) ≠ -f(x)

It is not an odd function.

Let's check the second function.

f(x) =

This is also not an odd function.

Clearly, iii) f(-x) ≠-f(x)

iv)

Now plug in x = -x, we get

f(-x) =

f(-x) =

f(-x) =

f(-x) = -f(x), this is true.

Therefore, the odd function is D) f(x) = 6x^3 + 2x

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

10

x=5

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
