Unformatted text preview: t(x) = 3x + 5 t(x + 1) would represent that a person would pay for one more than the number of drinks consumed (horizontal shift, left 1) t(x) + 1 would represent raising the cover charge by $1 (vertical shift, up 1) Proving whether a Function is even, odd or neither Proving even: A function is even when f(x) = f(-x). When a function is even its graph is symmetric over the y-axis Ex. f(x) = x - 9x Proving odd: A function is odd when f(-x) = -f(x). When a function is odd its graph is symmetric over the origin. Ex. f(x) = 4x - 5x A function is neither even or odd when neither of the proofs work...
