Which example illustrates the commutative property of addition for polynomials? (2x2 + 5x) = –(–2x2 – 5x) (2x2 + 5x) + 0 = (2x2 + 5x) (2x2 + 5x) + (4x2 – 4x) = 2x2 + 5x + 4x2 – 4x (2x2 + 5x) + (4x2 – 4x) = (4x2 – 4x) + (2x2 + 5x)

Suppose you want to transform the graph of the function y=tan(x+pi/4)-1 into the graph of the function y=-tan(x+pi/2)+1 which transformations should you perform. a) reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up. b) reflect the graph of the first function across the x-axis, translate it pi/4 units to the right, and translate it 2 units up. c) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the left, and translate it 2 units up. d) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the right, and translate it 2 units up.
