Answer
a) see graph below
b) graph resembles that of exponential functions
c) not linear
Work Step by Step
a) The graph of the data points $\{(1,1), (1.5,1.5), (2,1.8),(2.5,3),(3,4),(3.5,5)\}$.
b) The graph of the data points increases from left to right. It resembles the graph of an exponential function.
c) The graph is not linear since for every constant increase in the value of $x$, the corresponding values of $y$ do not increase by a constant value.
