You may assume that two-dimensional graphs are in the usual Cartesian xy -plane. Give exact answers, unless you are told to approximate. SHORTER PROBLEMS (21 POINTS) 1) (6 points). Write the domain of f , where fr () = r ± 5 r ± 7 + r 3 , using interval form (the form using parentheses and/or brackets). 2) (3 points). The graph of y = 2 x 5 + 3 x 3 ± x is symmetric about the …. (Box in one:) x -axis y -axis origin (none of these) 3) (3 points). Find functions g and f such that f ± g x = 4 x + 5 3 . You may not use the identity function. Fill in the blanks: gx = ____________ fu = ____________ 4) (3 points). If the point 3, ± 5 lies on the graph of y = fx , where f is a one-to-one function, what point must then lie on the graph of y = f ± 1 x ?
