Interpret the parameters in a linear (𝑓(𝑥) = 𝑚𝑥 + 𝑏) and exponential (𝑓(𝑥) = 𝑎 • 𝑑ˣ) function in terms of context. (In the functions above, “𝑚” and “𝑏” are the parameters of the linear function, and “𝑎” and “𝑑” are the parameters of the exponential function.) In context, students should describe what these parameters mean in terms of change and starting value.
