, that is ceiling function.
Hi there, I'm trying to do this question but I'm stuck:
Graph the function:
f(x) = (2/3)^{x}, -4≤x≤1, x∈R
f(-2) lies in the range [1, a]. If a ∈ N, then what is the minimum value of a?
I've drawn the graph, but I don't understand the second part of the question. Could someone please help me?
