b. Using a scale of 2cm to lunit on the x axis and 2cm to 2units on the
y axis, draw the graph of the function
c. On the same axes and using the same scale, draw the graph of
y=2x+1.
d. Use your graph to estimate;
1. The roots of the equation x?-x-2=0
il. The least value of the function y=2x-3
III. The value of x corresponding is the least value of y.
