B2. Take S to be the set that is given by S = {(x, y): x + y 1}. Take f to be the function that is given by f = {(x, 2x 7x+5): s ): s R}. Transform S to obtain a set E and f to obtain a set 9 by scaling the x-axis by a factor of 5 and by scaling the y-axis by a factor of 3, and then by translating the resulting sets by the vector (4, -1) (a) Find an equation that describes E. (b) Find an equation that describes g.
