Question

Find the domain and range of the function. f(x) = 9x² + 3 domain range

Answer 1

Answer:

Domain: all real numbers, or (-oo, oo)

Range: (3, oo).

Step-by-step explanation:

The domain is the set of x-values that work when plugged into a function. Here, all values when plugged in produce a real answer, so the answer is all real numbers, or (-oo, oo).

The range is the result of the domain, or the y-values. Since the x^2 will only produce positive numbers, the lowest y-value we can get is 3, and the highest y-value we can get is infinity. So, the answer is (3, oo).
