Given the functions below, which of the statements are true: f(x) = -1/2x + 5 g(x) = -1/2x + 7 h(x) = -2x + 3 k(x) = 1/2x - 13 Select an answer and submit. For keyboard navigation, use the up/down arrow ke a. k(x) is parallel to h(x) and g(x) is perpendicular to h(x). b. f(x) is parallel to k(x) and f(x) is perpendicular to h(x). c. f(x) is parallel to g(x) and f(x) is perpendicular to k(x). d. g(x) is parallel to k(x) and g(x) is perpendicular to h(x).
