Question

Which of the following represents the graph of f(x) = 3^x + 1?

Answer 1

The given function is:

`f(x)=3^x+1`

It is required to choose which of the graphs represents the graph of the function.

To do this, find the y-intercept of the function by substituting x=0 and then compare it with the y-intercepts of the graphs.

Substitute x=0 into the equation of the function:

`f(0)=3^0+1=1+1=2`

Hence, the y-intercept is 2.

The graph with the y-intercept 2 is the required graph.

The graph is:
