Let h be a function whose graph coincides with the straight line y=2x+1 at every point except x=2. At x=2, the graph shows only the single plotted point (2,5).
(i) Find x→2limh(x).
(ii) State the value of h(2).
(iii) Are the two values obtained in (i) and (ii) equal?
a. (i) x→2limh(x)
b. (ii) h(2)
c. (iii) Comparison of the two values
