It's okay. :) Still need help?

Answer 5

yes please! i actually have 4 that i need help with

Answer 6

Alrighty, well let's see the first one ^_^

Answer 7

What transformation has changed the parent function f(x) = log3x to its new appearance shown in the graph below?

Answer 8

Could you attach the graph? :D

Answer 9

First, you need to know that the graph of \[f(x)=\log_3x\] looks like this.

Answer 10

Next, you need to know the difference between adding or subtracing INSIDE the function and OUTSIDE the function. Do you remember what your lesson said about that? :)

Answer 11

no :( Im just trying to do my math quickly because i have to finish a huge project due tomorrow

Answer 12

Okay, no problem.
A number adding or subtracting inside the parentheses of a function creates a horizontal shift. Such functions are written in the form f(x – h), where h represents the horizontal shift.
If the number is being subtracted from x, the graph will move to the right that many units. And if the number is being added to x, the graph will move to the left that many units.
For example, if it's f(x+3) that would move the graph to the left 3 units.
Get it? :)
Now, if we are working on the outside of the function, it will affect the graph vertically. (Subtraction making it move down and addition making it move up.)

Take another look at the graph I posted of the original function then look at your new graph. Which way did the graph move? :)

Answer 13

So would it be B? @KamiBug

Answer 14

no wait. D

Answer 15

Close. The graph did move vertically. But choice D would suggest it moved up. It actually moved down so we'd be subtracting. :) Notice how in my graph there is a point at (3, 1). Then in your graph that same point ends up at (3, -1). Get it?

Answer 16

Oh okay

Answer 17

So it would be C? @KamiBug

Answer 18

Yes, perfect. :)

Answer 19

Okay Thank you ! i have one more that i need reassurance on
@KamiBug

Answer 20

Okay! :D Ask away.

Answer 21

@kamibug

Answer 22

Can you try to show me what the parent function looks like? :)

Answer 23

Sorry for replying late, by the way. I reccomend a good graphing program like Desmos for these problems. :)
