(a) The inverse is when you swap the variables and solve for y. g(t) = 2t - 1 (Note: g(t) represents y) rewrite as: y = 2t - 1 swap the variables: t = 2y - 1 solve for y: t + 1 = 2y = y Answer for (a): =
(b) Same steps as part (a) above: h(t) = 4t + 3 rewrite as: y = 4t + 3 swap the variables: t = 4y + 3 solve for y:
Answer for (b): =
(c) replace all t's in the equation with = = = = Answer for (c): =
