Q. The graph of a sinusoidal function intersects its midline at (0,5) and then has a maximum point at (π,6).Write the formula of the function, where x is entered in radians.f(x)=□
Amplitude calculation: The amplitude is the distance from the midline to the maximum, so it's 6−5=1.
Phase shift determination: Since the graph intersects the midline at (0,5), the phase shift is 0.
Period calculation: The function has a maximum at π, which means the period is 2π, so B=1.
Midline identification: The midline is the D value in the equation, which is 5.
Function equation formation: Putting it all together, we get f(x)=Acos(Bx+C)+D, where A=1, B=1, C=0, and D=5.
Final function equation: So the equation of the function is f(x)=cos(x)+5.
