The graph goes through (0, 0), so is a sine function (not a cosine function). The maximum is 1 and the initial slope is negative, so the factor A is -1.

The extreme value is reached when x = π/4. We know the extreme value of -1·sin(α) will be reached when α = π/2. Thus α = 2x, and the factor B is 2.

Your equation is
  y = -1·sin(2x)

3(4x - 2) = 2(6x - 3)

12x - 6 = 12x - 6

Add 6 on both sides

12x = 12x

Divide by 12 on both sides

x = x

That means this has infinite solutions. Your answer is B.
