make sure to change "complex valued plot" which is confusing to "real valued plot" on the small dropdown by the graph

Answer 4

or use geogebra.

Answer 5

Geogebra is better than wolfram in this case. YOu can assign variables a, b, c and d

then graph

f(x) = a*log_(b) ( x- c) + d

Then see what happens as you change a, b, c, and d.

Answer 6

i have to download geogbra though :(

Answer 7

NO you don't. YOu can run it through the web.

Answer 8

Also if you make only one math download EVER -- geogebra is worth it.

Answer 9

But you do not even have to download it. Just use the "Webstart".

Answer 10

or do the following
draw the basic graph of a logarithmic function
shift 3 units right
make it somewhat steeper as you are multiplying by 3
move it one unit up

Answer 11

a third possibility is to use a graphing calculator
it will probably not have log base 4, but you can get around this by graphing
\[y=\frac{3\log(x-3)}{\log(4)}+1\]

Answer 12

yea so i needed points so i got (2,5) thnks to wolfram but i cant get another one

Answer 13

can you give another point on the graph not decimals though

Answer 14

wait 2,5 is wrong too >:(

Answer 15

i cant estimate it wants exact points ;(

Answer 16

Here, I just made this for you: : http://www.geogebratube.org/material/show/id/13637

No download required. Click "student worksheet" and you're good to go.

Answer 17

oooo wow thanks

Answer 18

No prob. :) I hope it's helpful. Really try to figure out what a, c, and d do...and what the base does. Change each individually until you get a feel for it.
