Question

Where is the function increasing?

Choose all answers that are correct.





A.


from x = −4 to x = −2


B.


from x = −2 to x = 1


C.


from x = 1 to x = 3


D.


from x = 3 to x = 4

Answer 1

In simple words, a function is increasing when the bigger is x, the bigger is y.
In your case it's true for

`x\in\langle-4,-2\rangle\\ x\in\langle3,4\rangle`

So the correct answers are A and D.

Answer 2

I would say from x=-4 to x=-2 and also from x=3 to x=4.
because those are the points where they are going up as in increasing, i think you get it ;)
so A and D would be your answers.

hope this helped :)
