5. A piece of a graph illustrated below appears'f to represent ? (1' We are only shown a piece of the graph so we are making our best guess!) (A) an even function (B) an odd function (C) a rule that is not a function (D) a periodic function (E) the sum of an odd and an even function 8. The graph below corresponds tol? ll'llll'll lilillilil (1' We may assume that the periodicity of the graph continues outside the narrow bounds of the window shown) (A) a compression of sin(;c) in the sic-direction by a factor of 1/4, followed' by a shift in the m-direction by +1r/4 units (B) a compression of sin(a:) in the sis-direction by a factor of 2, followed by a shift in the m-direction by +1r/4 units (C) a compression of sin(:l:) in the :zz-direction by a factor of 1/2, followed by a shift in the m-direction by +1r/4 units (D) a compression of sin(:c) in he wdirection by a factor of 1/2, followed by a shift in the mdirection by +1r / 2 units (E) a stretch of sin(:1:) in the mdirection by a factor of 2, followed by a shift in the :cdirection by 1r/4 units
