Hmmm.....
Find the indefinite integral of 1/1+squareroot(x)
Have you finished it?here is a nice graphs question. Graph the function <a href="http://www.codecogs.com/eqnedit.php?latex=y^2=x^3(x-2)" target="_blank"><img src="http://latex.codecogs.com/gif.latex?y^2=x^3(x-2)" title="y^2=x^3(x-2)" /></a> noting the behaviour of the curve near its intercepts. (you dont need to mark inflection points) (don't cheat and use wolfram)
also, nightweavers question takes ages fuuuuuuuuuuuu
yes, im definitely not scripting the solution though haha. I used cartesian co-ordinates, parametric might have made it easier.Have you finished it?
And how would I determine the domain and range and draw it on a graph?
We know that the expression inside square root is always positive, (can be equal to zero too)
thanks for the answer spiral! I should have mentioned I got that far, but I am not sure how to determine the domain and function and how i would d
And for f(x)
As it is always positive (can be equal to zero)
he just solved for domain and range, x=>3, y=>0. the graph is the positive axis of a sideways parabolaAnd how would I determine the domain and range and draw it on a graph?
ohhh ok! thanks so much!And how would I determine the domain and range and draw it on a graph?
This thread is for MX2 questions.What is the congruent of 2 root 3 + 3 root 7?
Thanks so much guys!! Sorry for the stupid questions!

If you have your own, make your own thread so you can ask as many questions as you like. Best not to hijack this one.
