2.5 Continuity
3. We would like to find a value of k to make the piecewise function f(x) continuous at x = 3.
f(x)=kVx+I, 0sxs3
15-x, 3<xs5
236 Drk
a) If you were to graph f(x), which part of the graph (left or right) is changed when k is
changed? How does the graph change?
b) Do you think there is a value 'of k for which the left and right pieces of the graph will
'match' at x 3?
c) If there is such a value of k, describe what must be true about the value of the left and
right hand function expressions at x 3.
