Transcribed Image Text:**Problem 7: Determine the Range of the Following Real Functions**
For the given functions \( f: \mathbb{R} \to \mathbb{R} \), identify the range. Remember to clearly denote the interval in your answer. For instance, with the function \( f(x) = x^2 \), the range should be specified as \( \{ x \mid x \geq 0 \} \), highlighting that \( x \) must be non-negative.
(a) \( f(x) = x + 2 \)
(b) \( f(x) = x^2 + 1 \)
(c) \( f(x) = 3 - x^2 \)
