the graph represents a function with the form f(x)=a sin(bx + c). which values of a, b, and c are possible…

Explanation:

Step1: Determine the amplitude

The amplitude of the sine - function (y = a\sin(bx + c)) is given by (|a|). The maximum value of the function is 6 and the minimum value is - 6. So, (|a|=\frac{\text{max}-\text{min}}{2}=\frac{6 - (-6)}{2}=6), which means (a=\pm6).

Step2: Determine the period

The period (T) of the function (y = a\sin(bx + c)) is given by (T=\frac{2\pi}{|b|}). From the graph, the period (T=\frac{2\pi}{3}). Then (\frac{2\pi}{|b|}=\frac{2\pi}{3}), so (|b| = 3), which means (b=\pm3).

Step3: Check the phase - shift (not necessary to determine the answer here)

We can check the phase - shift, but from the amplitude and period calculations, we can see that (a = 6,b = 3) is a possible combination among the given options.

Answer:

B. (a = 6,b = 3,c=\pi)
