QUESTION 1
Find the intervals over which the given function is increasing, is decreasing, or is constant.
f(x) = 2x + 5
o increasing on 50,0)
constant on (2,5)
decreasing on (0)
decreasing on -- 2/5), increasing on (2/5,

a. is correct

70

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
