Transcribed Image Text:For reasons not yet fully understood, the number of fingerling salmon that survive the trip from their riverbed spawning grounds to the open ocean varies approximately sinusoidally from year to
year. The table shows the number of salmon that hatch in a certain British Columbia creek and then make their way to the Strait of Georgia. The data is given in thousands of fingerlings, over a
period of 16 years. (Let t represent years since 1985.)

Expression, rule, or law that gives the relationship between an independent variable and dependent variable. Some important types of functions are injective function, surjective function, polynomial function, and inverse function.
Expert Solution
Step 1
Consider the given table.
Step 2
The number of salmon corresponding to year 1985 is 43.
Graph (a) The number salmon is between 40 to 50. So the graph may be correct.
Graph (b) The graph to the top right. The number salmon is between 30 to 40. So the graph is incorrect.
Graph (c) The to the bottom left. The number salmon is between 40 to 50. So the graph may be correct.
Graph (d) The number salmon is between 50 to 60. So, the graph is incorrect.
Now the left option are Graph (a) and Graph (c).
