Hi, I'm currently preparing for a math assignment at school and came across this problem. We only did the A's, and I knew how to find the answer back then, but here? I have no idea, and something like Photomath unfortunately doesn't help either. Thank you in advance
Hey, I can't get any further right now. To calculate the maximum domain, you set the denominator of the fraction equal to zero. However, I don't know how to calculate this further… The solution is Df=R\{5; -2}, but how do I calculate that? Thanks for all the answers!
This is exercise 7 b) on the worksheet in Appendix 1. Appendix 2 contains the domain of definitions as our teacher provided the solution. I'm very confused and don't know how to arrive at this. Note that this is a contextual domain of definitions! I would be happy about explanations 😀
Good day, I need some help with the following problem, as my calculation method doesn't match the sample solution. Below is an image of the problem, an image of the sample solution, and an image of my calculation. I look forward to your help.
