The equation for the function is y = 0.5 · sin (x + 0.5π) + 1, found by evaluating the expression and comparing its results with the graph. (Correct choice: B)
<h3>How to determine the sinusoidal function related to a given graph</h3>
In this question we must determine a function associated to the graph, the quickest approach consists in evaluating each choice. The correct choice contains the three points presented in the figure.
After a quick analysis we find that the function is y = 0.5 · sin (x + 0.5π) + 1, which is proved by direct evaluation:
x = 0
y = 0.5 · sin (0 + 0.5π) + 1
y = 0.5 · sin 0.5π + 1
y = 0.5 + 1
y = 1.5
x = 0.5π
y = 0.5 · sin (0.5π + 0.5π) + 1
y = 0.5 · sin π + 1
y = 1
x = π
y = 0.5 · sin (π + 0.5π) + 1
y = 0.5 · sin 1.5π + 1
y = - 0.5 + 1
y = 0.5
The equation for the function is y = 0.5 · sin (x + 0.5π) + 1, found by evaluating the expression and comparing its results with the graph. (Correct choice: B)

Answer:
11
Step-by-step explanation:
4 × (2 3/4) = 4×2 + 4×(3/4) = 8 + 3 = 11
or
4 × (2 3/4) = 4 × 11/4 = 11
