Question

Which of the following represents the graph of f(x) = 3x − 2?

Answer 1

Option 2

Explanation:

Given : Function
`f(x)=3^x-2`

To find : Which of the following represents the graph of f(x)?

Solution :

To determine the graph we have to find the points through which the function passes.

The given function is an exponential function.

`f(x)=3^x-2`

Points

x f(x)

-2 -1.889

-1 -1.667

0 -1

1 1

2 7

From the given graph we see that in graph 2 satisfy the points.

Therefore, Option 2 is correct.
