Maths C3 - Help with Functions Question...?
Ok so this question is taken from the Edexcel C3 Modular Maths Textbook - Exercise 2E Question 5.
Can someone look through my answer and tell me whether I'm right or what I can do to improve? I really struggled with this question and am not really sure if what I've done would get me the marks in a real exam. I mean, I don't really understand why x>a where a=-2 surely that would make the graph of m(x) only half of a parabola?
here are my answers...
