Final answer:
The equation y = -|x| + 3 is an absolute value function, identified by the presence of the absolute value operation on the variable x.
Step-by-step explanation:
To identify the type of function represented by the equation y = -|x| + 3, one must look at the operations and terms within the equation. The presence of an absolute value operation (|x|) signifies that the function involves taking the absolute value of the variable x, which characterizes an absolute value function.
Therefore, the correct answer is C) Absolute value function. This type of function typically exhibits a V-shaped graph, with a linear increase/decrease on both sides of the vertex point, which in this case would likely be shifted by the +3 in the equation.
