Answer:

Step-by-step explanation:

Answer:

odd function

Explanation:

   To determine if a function f(x) is even/odd consider the following.

   • If f(x) = f( -x) , then f(x) is even

   Even functions are symmetrical about the y-axis.

   • If - f(x) = f(-x) , then f(x) is odd

   Odd functions have symmetry about the origin.

   Test for even function

   f(−x)=4(−x)3=−4x3≠f(x)

   Since f(x) ≠ f( -x) , then f(x) is not even

   Test for odd function

   −f(x)=−(4x3)=−4x3=f(−x)

   Since - f(x) = f( -x) , then f(x) is odd

   graph{4x^3 [-10, 10, -5, 5]}

Answer:

f(x) is an odd function

Step-by-step explanation:

Determine whether the function f(x)=4x^3 is even or odd

f(x)= 4x^3

To check whether f(x) is even then f(-x)= f(x)

To check whether f(x) is odd then f(-x)=-f(x)

Plug in x with -x and check whether it is odd or even

f(x)= 4x^3

f(-x)= 4(-x)^3=-4x^3

f(-x) is not equal to f(x). So f(x) is not an even function

f(x)= 4x^3

f(-x)= 4(-x)^3=-4x^3

f(-x) =-f(x)

So it is an odd function

Answer: In my answer I got 9 because the formula to find the area it would be A=1/2b*h



Step-by-step explanation: How would you do this?

Well we know that the base equals 6 we have heighth so we would have to do 1.5*6 and that would give us 9 but if we round it would be 10 because 9 is closer to 10 than it is to 0.


thanks :)

Needed help with a algebra 2 question if so...
erma4kov [3.2K]

Answer:

Quadrant II

Step-by-step explanation:

Since there are 360 degrees in a circle we will subtract it from 860 until we get a number less than 360

860-360=500\\500-360=140

Since it less than 180 but more than 90 it will be in the second quadrant

Hope this helps! <3
