Answer:
B. Increasing in x < -1 and decreasing in x > -1.
Step-by-step explanation:
We are given the graph of a function and is required to find the interval in which the function is increasing, decreasing or constant.
Now, from the graph we can see that the critical point i.e. the point at which the graph changes the direction is x = -1.
We observe that the function on the left side of x = -1 is going upwards to reach the point x = -1 and the function on the right side of x = -1 is going downwards.
Hence, we get that the function in increasing in x < -1 and decreasing in x > -1.
Answer:
The substitution method consists of solving for in one of the equations, basically the one that is easiest, and substituting the resulting expression in the other. With this, the second equation is converted into a linear equation with one unknown, which is solved by simply solving for.

Use the point-slope formula
y-y1=m(x-x1)
y-1=-3(x-1)
y-1=-3x+3
y=-3x+4
P = 2H + 2L
L = 6
P = 18
18 = 2H + 2*6
18 = 2H + 12
6 = 2H
H = 3 ft
The domains for this equation are (2,3,4,5) and the ranges for these equations are (1,2,1,3), so because there is no repetition for the x values, then k,-1 is a function. I say this because (2,1)= (-2,-1), (3,2)=(-3,-2), (4,1)=(-4,-1), and (5,3)=(-5,-3), so there is still no repeating x's. so, yes
