Anyway as c approaches + y should approach -
That is how you know it is decreasing
Find which one of those are.

Answer 15

start with the first one
increasing or decreasing

Answer 16

decreasing is coming from a biggest height to lowest
so increasing is going from lower to highest
i'm concerned about the height of the graph

Answer 17

Sorry i'm here i think its B and C

Answer 18

lets our function is f(x)=-x+1
the height of f when x=4 ==> f(4)=-3
the height of f when x=5 ==> f(5)=-4
so the height seems to decrease since -3>-4

Answer 26

you asked in your first comment what does it mean for a function to be increasing or decreasing here the formal definition of that
f is decreasing on the interval [a,b] if and only if a<b and f(a)>f(b)
f is increasing on the interval [a,b] if and only if a<b and f(a)<f(b)
