Question

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

Answer 1

Second graph is the required graph.

Explanation:

We have been given a function:

`f(x)=4(1.5)^x`

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.

Answer 2

Assuming the function is f(x)=4(1.5)^x, the answer is the second graph.

Both of the graph looks like a^x graph but you seem to put the function incorrectly. If the function is f(x)=4(1.5)^x, the value when x=0 would be:

f(x)=4(1.5)^x
f(0)=4(1.5)^0
f(0)=4*1= 4

The y-intercept should be 4
