Question

For which intervals is the function increasing? Select each correct answer.

(2, ∞)
(1, 2)
(0, 1)
(-∞, 0)​

Answer 1

i think the answer may be (2,infinity)

Answer 2

Answers: B and D

(1, 2)​ and (-∞, 0)​

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

Step-by-step explanation:

The function curve is increasing when going uphill as you move to the right. This happens on the interval (-∞, 0)​ aka -∞ < x < 0​ aka x < 0. This is why choice D is one of the answers.

The function is also increasing when 1 < x < 2 which translates to the interval notation (1,2). This is why choice B is the other answer.

Choices A and C are eliminated since they describe decreasing intervals.
