Which best describes the end behavior of y=-2x^3? as x > 0 increases, f(x) increases. as x < 0 decreases, f(x) increases. as x > 0 increases, f(x) decreases. as x < 0 decreases, f(x) decreases. as x > 0 increases, f(x) increases. as x < 0 decreases, f(x) decreases. as x > 0 increases, f(x) decreases. as x < 0 decreases, f(x) increases.

Choice D

As x increases, f(x) decreases; As x decreases, f(x) increases

==========================================================

This is an odd function (not odd as in strange, but odd as in not even). So the end behavior of this function has the left side going to positive infinity and the right side going to negative infinity.

Informally, it rises to the left and falls to the right. Check out the attached image for the graph.

More formally, as x gets larger, then y = f(x) gets smaller. In reverse, if x gets smaller or more negative, then y = f(x) gets larger. The negative out front of y = -2x^3 is the reason why x and y go in opposite directions for the end behavior (one gets larger while the other gets smaller).

i got 142 as my answer

step-by-step explanation:

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
