Chapter 10: Q. 112 (page 1019)

In the following exercises, match the graphs to one of the following functions:
$ⓐ 2^{x} ⓑ 2^{x + 1} ⓒ 2^{x - 1} ⓓ 2^{x} + 2 ⓔ 2^{x} - 2 ⓕ 3^{x}$
The given graph is,

Short Answer

Expert verified

The correct match is, $(c) 2^{x - 1}$ .

Step by step solution

Step 1 Given functions are,

$ⓐ 2^{x} ⓑ 2^{x + 1} ⓒ 2^{x - 1} ⓓ 2^{x} + 2 ⓔ 2^{x} - 2 ⓕ 3^{x}$

The given graph is,

The objective is, we need to find the function which should matches with the given graph.

Step 2 From the graph it is clear that the given graph is of an increasing exponential function.

The standard form of the function is, $f (x) = 2^{x}$ .

In the graph it is observed that, the graph is shifted horizontally right by $1$ units. So the function is,

$f (x) = 2^{x - 1}$ .

So, the correct match is, $(c)$ .
