Sr? - 4.0 +5 if x > 2 8. In all of this question let f(x) = { CPI-C if I <2 The letter c is a constant. (a) Find all values of c that makes the function f continuous at I = 2. Sufficiently justify your answer. [7 points) (b) On the same axis, make a sketch of the graphs of the function f for the values of c you found in Part (a). A tangent line to the curve y = f() has y-intercept of - 4. Find the equation of this tangent line. (10 points)
