Question

Help on two Pre calc question pleaseee???

Answer 1

Hmmm they both look like tangent functions. What is that silly little electricity looking break on the first graph? XD

Answer 2

I have no idea it came that way!! ;) haha any idea on how to solve them?

Answer 3

So in the first one, we can figure out the period of the function based on how long it takes to repeat.

I guess the easiest point to look at would just be where it crosses the x-axis.
So it crosses at \(x=6\pi\) then again at \(x=7\pi\).
So that function would have a period of \(\pi\).

Hmm you'll want to remember some of your basic trig graphs.
I think this one lines up with the tangent function.

But ummmm let's think about what's happening by the origin so we can make sure it lines up correctly.

Tangent goes through the origin. Would this function as well? :o

Answer 4

Yah it looks like it. It'll go through \(5\pi\), \(4\pi\), \(3\pi\), \(2\pi\), \(\pi\) and \(0\pi\).

I'm pretty sure the first graph is just \(y=\tan x\).
It doesn't appear to have any transformations applied to it. Hmmmm D:

Answer 5

@zepdrix that would make sense actually, we've been doing a lot of work on finding equations from Graphs, it's just hard for me to understand :(

Answer 6

Hmm :c

Answer 7

This first one is kinda tricky. I think they wanted you to try and figure out which function it is without knowing exactly what it looks like about the origin.

If you know what it looks like about the origin you can probably just match it up with one of the trig graphs that you remember.

So in this first one, they want you to notice the SHAPE that it has (it still is the tangent function based on it's shape) and label any transformations that have been applied to it (shifts to the right, left, up, down, or scaling).


Hmmmmmmmm let's check out this second one a sec :O
