Question

The graph of a function is shown below. on which interval is the function decreasing and linear

a.between x= -9 and x= -6
b.between x= -6 and x= -1
c.between x= -1 and x=3
d.between x= 3 and x=9

Answer 1

a

Explanation:

linear means a straight line segment

there are 2 on this graph, one on the left and one on the right.

decreasing means y decreases as x increases

this is the case for the line on the left, which is decreasing in the interval

between x = - 9 and x = - 6
