Recall: A function from one set of numbers (say X, the domain) into another set of numbers (say Y, the range) is a relation that guarantees each number in X is related to one (and only one) number in Y Guiding Question 1 Determine whether the graph is that of a function. If it is then use the graph to find the domain, range, any intercepts, and symmetry with respect to the x- axis, the y- axis, or the origin. (a) (b) Guiding Question 2 For ( 29 2 2 x f x x = - answer the following questions. (a) Is the point (3, 6) on the graph of f ? (b) For 2 x = - what is ( 29 f x ? What point is on the graph of f? (c) If ( 29 3 f x = , what is x ? (d) What is the domain of f ? (e) List any intercepts and zeros of f . Guiding Question 3 (a) State the intervals where the function is increasing, decreasing, or constant
