On the third question it also asks to find a value of x for which f(x) is not defined. I believe it would be -0.5, as 2 x -0.5 = -1, and 1/-1 + 1 is undefined.
i had done 5-a-day till august but a common pattern i found was some of the questions were actually really bad by that i mean the questions were not solve able, leading me to quit the 5-a-day program (i am only talking about the higher plus worksheet)
I agree, have done a fair few higher plus sheets with my students and some are a bit unrealistic compare to exams. Good on you for keeping up to the 5 a days tho! Will definitely pay off

Sorry, which sheet are you referring to?
Higher plus tier, sorry for not specifying.
Sorry yes i completely missed that question! You’re absolutely right, a 0 on the denominator makes it undefined, so x would be -0.5.
Well done!
This is such a useful video thanks
Thank you! Glad i could help, good luck in exams!
thanks

Hey man, would this be benificial for someone who is doing IGCSE edexcel ?
Definitely! To be honest, all of maths is the same across boards and qualifications, so any practice is good pracice
