The graph of \(ƒ(x) = 3x + 21 + 4\) relates to its parent function as follows:
C. The parent function has been translated up.
Explanation:
1. The parent function of \(ƒ(x) = 3x + 21 + 4\) is the linear function \(ƒ(x) = 3x\).
2. In the given function, the constant term "+21" shifts the graph of the parent function 21 units up along the y-axis.
3. Therefore, the correct answer is C, indicating that the graph has been translated up compared to the parent function.
