Section 3.6 Functions 277 Use the vertical line test to determine if each relation is a function. (See Objective 3.) 48. Find c(-2) if the function c(x) is given by Y1. 49. Find f (-3) if the function f (x) is given by Y1. 50. Find f (-2) if the function f (x) is given by Y1. 51. Find x if c(x) = -4 and the function c(x) is given by Y1. 52. Find x if f (x) = 3.4 and the function f (x) is given by Y1. 53. Find f (-4) if f (x) is given by the graph. 4 2 8 4 –4 –6 –4 –2 –8 x y 33. 34. 6 4 2 y –4 –2 2 4 x 35. 36. 37. 38. 6 Evaluate each function at the given value.
