IA1.AT.D.16: Analyze how changes to a function’s input or output affect the graph and its meaning in context. a. Identify how replacing f(x) with f(x + k) and f(x) + k changes the graph of a linear, exponential, or absolute value function. Describe the direction of the change and determine the value of k when given a graph. b. Explain how changing the input or output of a function affects the quantities represented in context. Use the structure and features of the parent function to justify how these changes impact the initial context.
