I NEED HELP ASAP! THANKS :)

Last option: increasing: -2 < x < 0 and x> 3/2;

decreasing: x < -2 and 0 < x < 3/2

Step-by-step explanation:

The function given is an absolute cubic function. (Pictured below).

We can determine from the graph that the equation increases over the interval:

increasing: -2 < x < 0 and x> 3/2;

decreasing: x < -2 and 0 < x < 3/2

 d) increasing from -2 to 0 and 3/2 to ∞

                     decreasing from -∞ to -2 and 0 to 3/2

Step-by-step explanation:

Graph the equation.  Then follow the path of the curve from left to right.  If you are going down, then it is decreasing. If you are going up, then it is increasing.

See image below. Blue represents decreasing. Red is increasing.

Note: If you are unable to graph the equation, then find the zeros of the equation, choose test points between the zeros, and plug them into the equation. If the test point is negative, then it is decreasing. If the test point is positive, then it is increasing.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
