write the equation of the trigonometric graph. try whole numbers or unit fractions for the value next to x…

Explanation:

Step1: Identify the vertical - shift

The mid - line of the cosine graph is the average of the maximum and minimum values. The maximum value of the graph is 5 and the minimum value is - 5. The mid - line is $y=\frac{5+( - 5)}{2}=0$. In the general form $y = A\cos(Bx)+k$, the value of $k$ represents the vertical shift. Since the mid - line is $y = 0$, the value of the blank after the cosine term is 0.

Answer:

$y = 5\cos(1x)+0$
