Question

The graph of g(x), shown below, is a vertical shift of the graph of f(x) = 2xWrite the equation for g(x).10289O A. g(x) = 2x-1B. g(x) = 2* + 1C. g(x) = 2* - 1D. g(x) = 2x+1

Answer 1

Solution

From the graph:

The graph was shifted downwards by 1 unit from the parent function f(x) as shown below

From the graph,

It can be seen that the parent function f(x) was shifted downwards by 1 unit to given g(x)

The equation of g(x) is

$g(x)=2^x-1$

Hence, the answer is option C
