Answer:
A has to be 2
Step-by-step explanation:
In the expression , the multiplicative factor A represents what is called the "amplitude of the wave-shaped function that you obtain as the graph. Such amplitude is understood as half of the crest-to-through distance of the wavy curve.
From the drawing, the crest is at y=2 and the through at y=-2 (a distance of 4 units) therefore the value of A should be half of that distance: 4/2 = 2

If you plug in the x and y values for the points (X,Y).
Then you are able to solve for the equation by seeing whether or not it equals the Y value.
Ex. Solving 9a.
Step One Equation and Point (2,0) or (X,Y)
Step 2 Plug in and solve
0=4-6+2
0=0
Done and Answer is Yes it does fit.
