3. h(x) = sin(x) - 2.5\namplitude: ______\nmidline: __________

Explanation:

Step1: Recall amplitude formula

For a function of the form $y = A\sin(x)+k$, the amplitude is given by $|A|$. In $h(x)=\sin(x)-2.5$, $A = 1$, so the amplitude is $|1|=1$.

Step2: Recall mid - line formula

The mid - line of a function of the form $y = A\sin(x)+k$ is $y = k$. In $h(x)=\sin(x)-2.5$, $k=-2.5$, so the mid - line is $y = - 2.5$.

Answer:

Amplitude: $1$ Midline: $y=-2.5$
