Point 7 — Increasing/decreasing linear or exponential functions

What do we see?

p% of f(x), f(x) increased by p%… linear or exponential models.

What do we understand?

Frame the equation before judging which model it is.

Question 1 of 1

If f(x) = 80% of x, for x > 0, then which is an appropriate model for f(x)?
