For each equation, determine whether its graph is symmetric with respect to the x-axis, the y-axis, and the origin. Check all symmetries that apply. X 5 (a) y-+x- 5=0 (b) xy = -3 Symmetry: Symmetry: O x-axis O x-axis O y-axis O y-axis O origin O origin O none of the above O none of the aboveSuppose that the functions s and t are defined for all real numbers x as follows. s (x) = 4x2 t (x) =x-4 Write the expressions for (t . s) (x) and (t+s) (x) and evaluate (t-s) (2). ( +.5) (x) = 0 ( + + s) (xx ) = 1 X ( t - s) (2 ) = 1
