Step-by-step explanation: The range of the function is the set of all its output values. To find the range of f(a) = 5 + 1/2a when the domain is (0, 4, 6), we can substitute these values into the function and see what the output is:
f(0) = 5 + 1/2 * 0 = 5
f(4) = 5 + 1/2 * 4 = 7
f(6) = 5 + 1/2 * 6 = 8
So the range of f(a) is the set of values {5, 7, 8}.
