Problem drawing graph, please help!
Hi everyone, I'm struggling to draw the graph of f(x) = 4/(x+3)
I'm just wondering how you go about plotting a graph like this and the process you use to do it. Thanks for your time
Excellent description there :) Beats my textbook! However I'm now just struggling to see how
9x^4 a^2 + 4x^3 a^3 = x^3 a^2 (9x + 4a)
As i'd work out x^3*9x, which would give you the 9x^4. But I'm not really sure how it'd then multiply out to give you the other terms, apologies as my...
So it would now become
x^4(9(3x-1)^2) + (3x-1)^3(4x^3) - i see my mistake there, my only problem now is how to simplify this further. How would i go about taking the factor out?
Problem with factorising
Hi, the question is to differentiate the following equation with respect to x.
x^4(3x-1)^3
Using the product rule i think i'v partially completed this to
x^4(3(3x-1)^2) + (3x-1)^3(4x^3)
I'm now required to simplify this - which leaves me completely stumped...
