..Cosider rational function f(x)= 2x^2 + 7x-5 / x+4
1. Determine if graph has any holes Mr F says: x + 4 is NOT a factor of 2x^2 + 7x - 5. Therefore no holes.
2. find all asymptopes for f(x) Mr F says: Vertical asymptote should be obvious (hint: when is f(x) undefined). Horizontal asymptote: None. Oblique asymptote: Hint: .
3. find all intercepts Mr F says: x-intercepts: Hint: Solve 2x^2 + 7x - 5 = 0 (why?). y-intercept: Should be obvious.
4. find atleast one point between any verticle asymptope(s) and x-intercepts(s) Mr F says: Draw the graph. I'd suggest a simple point like one on the x-axis ......
Thanks for your help or answers I really need to catch up on studying. Mr F says: Yes you really do.
