Find the domain and range of the function. (Enter your answers using interval notation.)

Question

f(x)= 4x² + 8,    0 ≤ x ≤ 2

Need the domain and range in interval notation. Thanks!

Answer 1

You're given the domain, the input. Since it includes the end points, you use parentheses.

(0.2)

The domain is the output if you put each of those numbers in your function. It will also use parentheses.
