(12) (6 puts) If the statement is true, please write true. If the statement is false, please write false. Q12a) If f (x) is an even function and f (7) = 20, then f (-7) = 20 Q12b) The domain of k(x) = vx + 2 is (-co, -2) U (-2, co) Q12c) f(x) = x5 - 2x2 is an even function Q12d) Even functions are symmetric with respect to the y-axis. Q12e) Odd functions are symmetric with respect to the x-axis. Q120) The graph sholen is a reflection of vx across the x-axis: 5 3- 2 5-4 -3 2 -1 0 1 2 3 4 5 3 -5
