Answer:
f(x) = x+3
Explanation:
a) For sketching the graph, we need to plot all the points on the XY plane.
Let x represents the time (in years) and y represents the height of the mountain Ash tree (in feet).
We plotted the graph through excel.
b) Using the trendline function in Ms Excel, we get the equation representing this graph
Equation is: y = 0.9783x + 3.6086
The function that models the graph will be calculated graphically that is,
f(x) = x+3
