Section 2.2 Let’s investigate the behavior of the function f defined by f (x) = x2 – x + 2 for values of x near 2. The following table gives values of f (x) for values of x close to 2 but not equal to 2. Section 2.2 Section 2.2 Section 2.2 "x is near a" Section 2.2 Section 2.2 Section 2.2 Section 2.2 Section 2.2 Section 2.2 The graph of a function g is shown in the Figure. Use it to state the values (if they exist) of the following: Section 2.2 Section 2.2 Section 2.2 The symbol limx→a f (x) = – ∞ can be read as “the limit of f (x), as x approaches a, is negative infinity” or “f (x) decreases without bound as x approaches a.” Section 2.2 Similar definitions can be given for the one­sided infinite limits Section 2.2 Section 2.2 Section 2.2 Section 2.2 Section 2.2 Section 2.2 Section 2.2
