The diagram shows the graph of the function [tex]f(x)=b^x.[/tex]
This graph is increasing, when b>1 and decreasing, when 0<b<1.
From this graph (in case 0<b<1) you can see that
- [tex]f(x)\to \infty,[/tex] when [tex]x\to -\infty;[/tex]
- [tex]f(x)\to 0,[/tex] when [tex]x\to \infty.[/tex]
Answer: correct option B.
Answer:
b)f(x) -->0, when x --->∞ and f(x)--->∞, when x--->-∞
Step-by-step explanation:
First let's draw the graph.
Here f(x) = b^x, when 0 < b < 1
Here b greater than zero and less than 1.
Therefore, b must be number which is less 1 and greater 0.
Let's take b = 1/2 and the function becomes f(x) = (1/2)^x
Now let's draw the graph to find the answer.
In the graph,
f(x) -->0, when x --->∞ and f(x)--->∞, when x--->-∞
Therefore, answer is b)f(x) -->0, when x --->∞ and f(x)--->∞, when x--->-∞
