Q. What is the period of the function f(x)=6sin(3πx+4)2 f(x)=-6 \sin (3 \pi x+4)-2 ?\newlineGive an exact value.\newlineunits
  1. Sine Function Period Determination: The period of a sine function is determined by the coefficient of xx within the sine function. The general form of a sine function is f(x)=Asin(Bx+C)+Df(x) = A \sin(Bx + C) + D, where the period is given by 2πB\frac{2\pi}{B}.\newlineIn the given function f(x)=6sin(3πx+4)2f(x) = -6\sin(3\pi x + 4) - 2, the coefficient of xx is 3π3\pi.
  2. Identifying Coefficient of x: To find the period of the function, we use the formula for the period of a sine function, which is 2π2\pi divided by the coefficient of xx. In this case, the coefficient is 3π3\pi. So, the period TT is T=2π3πT = \frac{2\pi}{3\pi}.
  3. Calculating Period Formula: We simplify the expression for the period by dividing 2π2\pi by 3π3\pi.T=2π3π=23T = \frac{2\pi}{3\pi} = \frac{2}{3}.
  4. Simplifying Period Expression: The period of the function is 23\frac{2}{3}, which is the exact value.
