For each function above write the domain and range in complete sentences using interval notation, (domain is about inputs or x direction and range is about outputs [results of the function] or y direction [If z(x) = Squareroot x - 6 - 2: the domain of z(x) is [6, infinity). the range of z(x) is [-2, infinity).]

Solution

If f(x) = 4x, the domain of f(x) is [0,). The range of f(x) is also [0,). If g(x) = (4x) +5, the domain of g(x) is [0,). The range of g(x) is [5, ). If h(x) = 3(x-2) -4, the domain of h(x) is [2, ). The range of h(x) is [-4, ). If m(x) = (x+8)1/3, the domain of m(x) is [-8, ). The range of m(x) is [0, ).
