Hello, Paymemoney!

Your algebra is off . . .

Quote:

Express in the form

and find the asymptotes of the following equations:

i got: . . . . no

We have: .

Complete the square: .

And we have: .

Divide by 16: .

To find the asymptotes, set the equation equal to 0.

. .

Take square roots: .

Therefore: .

can someone tell me where i have gone wrong in finding the x-intercepts for question 1.

so x=0 or x=2

i looked in the book's answers and it says and - Jan 16th 2010, 09:15 PMProve It
