Mathematics for IGCSE & O level - Sketching Curves (Section 2 - No. 7)
What information is needed to sketch the graph of y = 1/x + 4? (Select all that apply)
The location of the asymptotes
The y-intercept
The turning point
The end behavior of the function.
Explanation
Knowing the asymptotes (x=0, y=4), the y-intercept, and end behavior (as x approaches +/- infinity, y approaches 4) is crucial.
