so i transferred to a new school and I'm collaborating with another pre-cal teacher. she is kind of helpful but i can tell she doesn't really want to share her work (even though collaboration is about helping each other out).
She already made a unit test, but i had to make my own answer key. I...
Here's my equation y= sqrt (x+4)+1
I want to find the x intercept. Ok so i replace y with 0 and solve for x
0= √(x+4)+1
-1=√(×+4)
(-1)2=×+4
1=×+4
-3=×
So it looks like the x intercept is (-3,0)
But then when i go back and plug in -3 in place of x...
y=√(-3+4)+1
y=1+1
y=2
I now have a point...
You're right some information is useful than others, but yet it still bothered me. I just want to make sure I understand as much angles as i possibly can about the concept of parametric.
Thank you for your insight! I can rest for a bit until the next question arises...
Wow!...perfect answer for my 1st question! I figured it so and when you brought up the x, y, t plane it made it all the more clearer! Thank you!
As for clarity on my second question…let’s see if I can rephrase it.
Let’s say f(t) is an equation of a horizontal parabola and g(t) is some...
...just introducing myself!
I am a high school math teacher (nothing exciting about that). I've been teaching for 6yrs. I taught algebra for 4 and half yrs and for the past year I've been given the opportunity to teach precal and geo. Teaching geo was pretty straightforward. Precal in the...
Hi everybody, i just joined. Here's my first post
I have a few questions.
When looking at curve C and by the eye test, it doesn't pass the VLT, even though x=f (t ) and y=g (t) are functions,...then overall with curve C not passing the VLT, is it still a function since f (t) and g (t) are?
I...
