your voice is really calming to do math to
-
its just pluging points in the equation, then solve for a and b and then put them together! i get this ! yay thx!
-
@Jhand1013 that is elimination... you can use either way :)
-
I still do not understand how to do this question:
What is the focal point given the following exponential function; (transformation of function y=5^x)
4/25^(x-4) * (1/8y - 3 ) = √[1/125^(-4x+8)]
-
I can't thank you enough..
ALL OF YOUR VIDEOS ARE EXTREMELY HELPFUL!!
-
THANK YOU SO MUCH. This helped me out A LOT. :)
-
can you possibly tell me what the "b" from the equation y=ab^t because that's the only thing my notes don't tell me and ironically its what i need for this assignment :)
-
This helped SOO much. Thankss :)
-
this is assuming there were no transformations other than vertical stretch right?
-
Thank you so much my teacher hasn't taught us something this useful yet...

I think my teacher showed it a different way. Placing one equation on top of the other, then dividing the two so the a's cross out and u subtract B's exponents and solve for them or something like that. I can't remember or find my notes on it though.

@Jhand1013 yes, that way is more efficient; however, i have found that many students also find it more confusing, so i show this method as well as it is 'more familiar' to most students.
