Hi I have a question, let's say y=t^2-5, t<4, why is the range y>5 for this and not -5<y<11, why are we not substituting the t=4 in y equation? (This was a question from edexcel ial p4 book). Thanks for your response in advance, may God bless you!

Can you do a video on range and domain of paramteric and cartesian equations

For question 4, y=9-t² t greater than 0, how does the range become y less than 9?

can you make a series for stats 2 as well ?
