Question

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

Answer 1

\[f(x)=b^x \]

Answer 2

HI!!

Answer 3

you want me to tell you, or you want to try two different values for \(b\) and see what happens?

Answer 4

Hello again.

Answer 5

I'd like to try working through this.

Answer 6

try two values for \(b\)
try \(b=\frac{1}{2}\) and \(b=2\)
you will see that one increases, the other decrease
check it

Answer 7

You're right. It does increase/decrease.

Answer 8

the dividing line is \(b=1\) for which you get a constant
so decreases if \(b<1\)increases if \(b>1\)

Answer 9

Okay. Thank you.
