so we sub x=a because in the graph it says (a,b) what if the question said (-a,b) ??

But the answer is f(x)=-(x-a)^3 +b ...

I am confused about using horizontal transformations such as f(x+a) and f(x-a) to interpret these graphs.

the fraction gets smaller, but don't we end up adding that to the value of c??well if a/(x-b)^2 +c let a=1 b=1 c=2 so we get 1/(x-1)^2 +2 lets make x =2 we get 1/1 +2 ... that's 3... wait am i doing something wrong? - - - Updated - - - oh wait is because in the above a is negative.. so...

I'm stuck at understanding why +c is the horizontal asymptote. Can someone please explain this? I get that the vertical asymptote is relating to (x+b), because the denominator cannot=0. But why does this kind of graph have a horizontal asymptote to begin with?

Can someone explain how these graphs are drawn. How does the value of p/q affect this graph? How does the domain and range change? How are the asymptotes found? The below is an image about what I'm talking about: Here is a question the deals with this type of graph (no idea how to solve it...

Can someone explain the following: How does changing the value of p/q affect the drawing of the graph (so domain/range/shape etc) What makes this graph an odd function? How to work out asymptotes? Heres a picture so you know what I'm referring to: And below is a question dealing with this...

Thank You! I just need some guidance. A textbook can only do so much, and my teachers have been...hmm...unsatisfactory. :)

wow mindblown. :O that was such a cool way of solving it! THANK YOU (Inlove)

is there an equation for symmetry in x-axis?

Can someone explain why the answer is D a < 0 because it finishes downwards e < O because the y-intercept is in the negatives. b, & d = zero (but i don't get this) c is supposedly > 0 (nor do i get this) According to the solutions the graph is an even function, and symmetrical about the...

There are a couple of things i didn't get in your explanation, and its due to my lack of vocab in calculus. :P this derivative has a root at x=0 (what do you mean root?) this roots is of even multiplicity (again, what is root/ multiplicity?) from the second derivative test for relative...

Hey guys, I'm interested in having someone who likes maths to discuss maths questions/solutions/concepts with myself. This is just to improve my understandings over the year. Message skype name below, or PM me for mine I'm interested in studying on...

Can someone explain the link between the turning point (local max, min & stationary point of inflection) and it's relationship to derivatives. Let me clarify what I understand (feel free to correct me). If we derive an equation and let it = 0, the value of x is some kind of turning point...

i fixed it :p read again, it was a mistake i forgot the x^2
