How do you graph the function f(x)=6^x? Explain it to me, please.

Question

anonymous · Answer

You use a graphing calculator.

anonymous · Answer

Is there any way to do it without one?

richyw · Answer

are you trying to sketch it, or do you want to make a proper graph of the function?

ranga · Answer

a^x  where a is a positive number greater than 1 all have the similar plot as e^x.
The function will always be positive and so the plot will be above the x-axis.
It will cross the y-axis at (0,1)
When x-> -infinity, f(x) -> 0.

I'm trying to sketch it but I don't have any graphing technology

if you just want to make a sketch of it, then what ranga said is good. This tells you all the important stuff about the function.

of course you could always make a table of values, and plot the points.

Just make a table, for f(x), 1,2,3,4 etc.

Plot them on the graph: 

f(1) = 6^1 = 6

(1,6)

f(2) = 6^2 = 36

(2,36) ... and so on

richyw · Answer

also, assuming you are on a computer, you do have graphing technology available.

It's a long story but I don't have it. But thank all of you guys for helping!! I think I can do it on my own now! :)
