Q. What is the midline equation of the function h(x)=−3cos(πx+2)−6
Identify Midline: The midline of a trigonometric function like h(x)=−3cos(πx+2)−6 is the horizontal line that represents the average value of the function over one period. To find the midline, we look at the vertical shift of the function.
Determine Vertical Shift: The vertical shift is given by the constant term that is added or subtracted from the trigonometric function. In this case, the constant term is −6.
Calculate Midline Equation: Therefore, the midline equation is simply y=−6, which is a horizontal line at the vertical position of −6 on the y-axis.
