Answer: a = 2 and b = 3.
Step-by-step explanation:
To find the values of a and b in the equation y = a sin(x°) + b, we need to use the information given in the graph.
From the graph, we can see that the amplitude of the function is 4, which means that |a| = 4/2 = 2. Since the function is a sine function, we know that it starts at the origin (0,0), which means that the vertical shift (b) is equal to 3.
Therefore, the values of a and b in the equation y = a sin(x°) + b are a = 2 and b = 3.
