Answer:
Step-by-step explanation:
Given is a graph with more than 2 periods shown. The wave represents that it is the sine function.
From the graph we find that the graph gets its maximum at y=-2 and minimum at y =-6
Hence range =[-6,-2]
Amplitude = 2
There is no x intercept but y intercept =-4
Hence the possible equation would be
y = 2sin(bx+k)-4
for some real b and k
Since sine max value is 1, we have
Maximum value is 2-4 =-2
