What is the equation of the midline of the sinusoidal function?

Answer:
2
Step-by-step explanation:
Well, to get the mid line of this Equation we need to understand the formula. The formula is [tex]\frac{max+min}{2}[/tex]
So the Max = 5
and the min = -1
So, [tex]\frac{5+-1}{2} =\frac{4}{2} =2[/tex]
