what is the midline equation of the function g(x)=3sin(2x - 1)+4? y =

Explanation:

Step1: Recall sine - function form

The general form of a sine function is $y = A\sin(Bx - C)+D$. The mid - line of a sine function in this form is given by $y = D$.

Step2: Identify the value of D

For the function $g(x)=3\sin(2x - 1)+4$, comparing it with $y = A\sin(Bx - C)+D$, we have $A = 3$, $B = 2$, $C = 1$ and $D = 4$.

Answer:

$y = 4$
