Water temperature affects the growth rate of brook trout. The table shows the amount of weight gained by brook trout over various days at different water temperatures.
Temperature (°C) Weight gained (g)
17.7 3.3
22.4 30.8
24.4 20.0
To estimate the weight gain at other temperatures, construct a table of estimated values for weight gain (W). Use the two-sided difference quotient with adjacent points for the first and last values, and the average of the two difference quotients with adjacent points for all other values. Round your answers to two decimal places.
Temperature (°C) Weight gained (g)
15.5 3.18
17.7
20.0 20.0
22.4
24.4
