\[\log_{3} (x)-1\] I just need the function that you type in

That IS what you type in. You already have what to type in. What calculator are you using?

geogebra... That's what they told us to use

log[3]{x} - 1 I think

is it a straight line? That's what I got
Hero

No, it wouldn't be a straight line

all logs or roots have curve lines. you can test it yourself graph the simplest of their forms y = x^2 y = x^3 y = x^5 y = x^(1/2) …. and so on

For the most part, the log graphs are going to be very similar with only minor differences with the base number change. Before any shift occurs, the point (1,0) always exists in a log graph and the y-axis is an asymptote. This is a general log graph: |dw:1378289196332:dw| Then from there, you just apply any shifts your graph my have. If the base is higher, like log base 100 or something, the curve will just be more like this: |dw:1378289311453:dw| Otherwise no huge differences. A graphing utility can just help you get more precision and certain points if needed, but not that must of a necessity for a basic graph ofit. Your function is log base 3 shifted down 1 :3

one way is to create a table x | y = x^2 --------------- -3 | 9 -2 | 4 -1 | 1 1 | 1 2 | 4 3 | 9 do the rest and see the patterns

Guys, I know you're trying to help, but I believe she wants to know how to graph it in Geogebra.

Thanks for your help, guys, but Hero is right... I just have to graph it and turn it in... Sorry

>.< there's always a hand out how to use graphing utility. refer to that manual or instruction for syntax. I use mathematica for myself, but my school requires crappy Maple and I have to learn using it.

For Geogebra, logarithm with base 2 is predefined...correct syntax is : ld(x) -1
anonymous
  • anonymous
and for any other base 'b' it would be log(b, x)
Hero
  • Hero
So @Sunshine447, literally you type log(3,x)-1
Hero
  • Hero
I know, because I just tried it. Great job @stgreen
