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

slega [8]

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

The equation of a circle uses the following formula:

$(x - h)^{2} + (y - k)^{2} = r^{2}$

The center of the circle is given by (h,k). Therefore, h = -2, and k = -5. r = 1, so we can find the equation from the information given to us.

Plug in your values.

$(x + 2)^{2} + (y + 5)^{2} = 1^{2}$

$1^{2} = 1$

The equation of this circle is as follows:

$(x + 2)^{2} + (y + 5)^{2} = 1$

A car traveled 360 miles in 4 hours. If its speed were to be 15 mph slower, how long would it take to travel the same distance?

docker41 [41]

Answer:

4.8 hours

Step-by-step explanation:

First, divide the distance by time to get velocity.

S = D/T

S = 360/4

S = 90 mph

Then, subtract 15 from 90 to get the new speed.

90 - 15 = 75

Lastly divide the distance by the new speed to get time.

T = D/S

T = 360/75

T = 4.8

Therefore, it would take the car 4.8 hours to travel 360 miles at 75 miles per hour.
