Thanks so much sir for the video. But where did all that energy go from old videos. I remember when u used to shadow box when teaching. 🤣🤣

when finding the range, why could you sub t directly into y, rather than subbing it into x and then subbing x into y

what if I found the method a different way and subbed x into the y equation from the start, it got the equation in terms of x and I got the same answer ie -8. Will i still get the marks
