First of all thanks a ton for all your hard work I am a B Ed student who got an interview call recently and I just had a few days to prepare for the interview By God’s grace I came to your channel, it’s helping me tremendously to brush up all my concepts in mathematics Well that said I had a doubt Ch 6 ex 6 3 question 14 We have two inequalities -2>0 and -4>0 And we have to find the values of a for which the function is increasing You said to choose min as -2 but if we do that we are leaving out all a between (-4,-2] so shouldn’t the answer be a>-4 Thanks for clarifying in advance, again I really appreciate the high quality work you are doing at no cost to your students Will be recommending your website to all my students too Cheers!
