To determine

To find: The statement which is true about $a$ and $b$ .

Answer to Problem 7.5STP

The condition is $a<0$ and $b>1$ .

Explanation of Solution

Given information:

The equation is $y=a{b}^x$ .

The graph is as follows.

  

Calculation:

As shown in the graph the graph is increasing in negative direction so the condition that is true about $a$ and $b$ will be $a<0$ and $b>1$ .

Therefore, the condition is $a<0$ and $b>1$ .
