The graph of a sinusoidal function has a maximum point at (0,5) and then has a minimum point at (2pi,-5). Write the formula of the function, where x is entered in radians. f(x)= ◻

Calculate Amplitude: The amplitude is half the distance between the maximum and minimum values. Amplitude = (5 - (-5)) / 2 = 10 / 2 = 5.Determine Period: The period is the distance between a maximum and the next minimum, which is 2pi. Period = 2pi.Find B: To find B, use the formula Period = 2pi / B. 2pi = 2pi / B B = 1.Identify Vertical Shift: Since the maximum is at (0,5), the graph is a cosine function shifted up by 5. D = 5.Determine A: The function has not been horizontally or vertically flipped because it starts at a maximum and goes to a minimum, so A is positive. A = 5.Identify Horizontal Shift: There is no horizontal shift because the maximum is at x=0, so C = 0.Write Equation: Write the equation using the values found for A, B, C, and D. f(x) = 5cos(1x + 0) + 5.

Calculate Amplitude: The amplitude is half the distance between the maximum and minimum values. $\newline$ Amplitude = $(5 - (-5)) / 2 = 10 / 2 = 5$ .
Determine Period: The period is the distance between a maximum and the next minimum, which is $2\pi$ . $\newline$ Period = $2\pi$ .
Find B: To find B, use the formula $\text{Period} = \frac{2\pi}{B}$ . $2\pi = \frac{2\pi}{B}$ $B = 1$ .
Identify Vertical Shift: Since the maximum is at $(0,5)$ , the graph is a cosine function shifted up by $5$ . $\newline$ $D = 5$ .
Determine $A$ : The function has not been horizontally or vertically flipped because it starts at a maximum and goes to a minimum, so $A$ is positive. $A = 5$ .
Identify Horizontal Shift: There is no horizontal shift because the maximum is at $x=0$ , so $C = 0$ .
Write Equation: Write the equation using the values found for $A$ , $B$ , $C$ , and $D$ . $f(x) = 5\cos(1x + 0) + 5.$
