Which graph best represents the function f(x)=4(1.5)x?

Answer:
Second graph is the required graph.
Step-by-step explanation:
We have been given a function:
[tex]f(x)=4(1.5)^x[/tex]
You can clearly see that y-intercept should be 4 according to the given function
In first graph y -intercept is 1.
In second graph y-intercept is 4
To find y-intercept put x=0
And to find x-intercept put y=0
So, put x=0 in the given function y=4.
You can see the attachment for the graph of the given function.
