Question

For what values of b is f(x) = b^x a decreasing function?

Answer 1

Let's say \(x\) is a positive integer to make the pattern more visible. What kind of number, when you multiply itself, gets smaller? Hint: It can be negative or positive, but its size (absolute distance from zero) is important.

Answer 2

"b" must be greater than 0 and less than 1

Answer 3

Okay.
