NCEA Level 1 Maths Tables, Equations & Graphs Tutorial - Exponentials

[@Kelly-kq5pl]

Thank you so much for making these videos! I have been really struggling with TEG especially with my teacher going over the concepts so quickly and brief. I have learnt so much from your videos and i find it so much easier to learn this way where i can pause and go back if i`m struggling with something. I feel a lot more prepared for tuesday now!

[@infinityplusone]

You're welcome and good luck!

Hey Subash my St Kent's students say you are a legend and a lifesaver! They are happy to hear your voice again !

[@infinityplusone]

Thank you Miss :) Happy to help.

[@kathryna8467]

Glad Dave is the new me. Wishing you all well.

[@s_seiya5987]

15:45 but I thought the difference between 100 and 66.66 is 33.34? Why is it 33.33 am I missing something here??

[@kathryna8467]

Thanks Subash, it's good to still hear your voice, and great explanation.

[@infinityplusone]

Dave has taken over your seat Miss! Missing you already!

I was taught that a = y-intercept i.e. the 0th term, but that doesn't seem to work with these questions.

[@infinityplusone]

Not if the graphs are moved up. That only works if there is no movement up or down

[@giselledenbreems3992]

@@infinityplusone ahh, that makes sense, thank you :)

[@juleswebb2129]

In the Exam does it matter if we use y = a*r^x + c or if we use y= r^(x-a)+c

[@infinityplusone]

Shouldn't matter which you use :)

Sup Jules

[@shanaya825]

can you please do a video about how to do angles in term of thanks

[@infinityplusone]

OK will find some questions

[@infinityplusone]

Sorry Shanaya Kumar, just ran out of time.

[@zaddydynamite]

How do you know if the x parthas +1 or minuse 1 ? like if the x is moving cause in all these scenariois the x is just x

[@infinityplusone]

I don't understand your question mate, could you tell me perhaps a time stamp and I can try & help.

[@zaddydynamite]

@@infinityplusone I mean You know How In general You substitute Two Points and put into a simultaneous eqaution to find c and a rigght? Nvmmm LOL it's hard to explain Dw Ty for the video

[@juleswebb2129]

Will this method of converting table to equation work for all exponentials?

[@infinityplusone]

Theoretically it should work :)

[@maiaoconnell2214]

These videos are great! Thank you so much for making them! I thought I was prepared for this exam but there are some huge gaps in my knowledge that the textbook I'm using just doesn't cover so this is amazing. One thing I'm confused about is how you would find an exponential equation for a graph that has been translated horizontally? How would you find the number to add to or subtract from the exponent, x?

[@chris2944]

If it's horizontally, saying youre moving the graph 2^x 2 units right, it's 2^(x-2), but if you're moving it 2 units up, it's (2^x) +2. He has other videos that will help.

[@chris2944]

Oi! *shhh!* I'm trying to make some quality content.

[@infinityplusone]

Hahaha yeah I think this video was in one of my classes
