Question: 4. State the domain and range of each function below. Explain your process. [A4] [C2] Function Reasoning f(x) = _ 13 4x+ 16+ 19 f(x)

4. State the domain and range of each function below. Explain your process. [A4] [C2] Function Reasoning f(x) = _ 13 4x+ 16+ 19 f(x) = _1 6x+ 81 99 5. Calculate the average rate of change for the function f(t) = 2 x 3 + 5 over the interval 1 x 2. [K3] 6. a. Use an x interval of 0.0001 to determine the instantaneous range of change of the function f(x)= x 4 + 8 x 3 + 19 x 2 + 12x at x = 2. Give answer to the nearest tenth. [A3] b. Determine whether the function f(x)= x 4 + 8 x 3 + 19 x 2 + 12x at x = 2 has a maximum or minimum at the point where x = 2. Justify your answer.
