Help me with 47-50 based on the graph

-1

3

[-4,-2] and [2,3] are increasing

[-2,-1] and [3,5] are decreasing

(-infinity,-4] and [-1,2] and [5,infinity)

Step-by-step explanation:

look at the graph

for 47. it's asking when the input (aka the X) is equal to 1, what is the output (aka the Y). so just go to the graph where X=1 and read the Y

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
