To determine the value of h in the function f(x) = ∣x − 21∣ + 4, follow these steps:

The given function is: f(x) = ∣x − 21∣+ 4

To match this to y = a∣x − h∣+ k:

Here, a = 1 (indicating no vertical stretch/compression or reflection).

h = 21 (because the expression inside the absolute value is x − 21, which matches x − ...
