1. So, I've been working on A level Further Maths summer work, and I've come across a question about x^3 graphs. What does having a x function added/taken away affect the graph? So what's the difference between y=x^3 and y=x^3+x? And how does the graph change as x increases?

Thanks
2. Well i assume you know what a x^3 would look like
For your second equation, try plotting the graph, it would have different solutions
Work out the max and min, stationary points and analyse the graph and try and figure out yourself rather then use the computer it'll feel more statisfying and teach you more

Thanks, but I don't really think you understood what I was asking
