Homework Help: X/y intercept for translations of f(x)

  1. Nov 11, 2004 #1

    please can you guys help me on this :

    f(x) = x^2 + 2x + 2


    In each of the cases above, I wanted to know given a function, does the graph of it change in terms of the x intercept , y intercept and vertex ?

    Does it depend on the particular function or not ?

    Thanks in advance.

    Why don't you first change that equation into transformation/vertex form
    f(x) = (x-h)^2 + k

    The make up numbers for a and see how it changes.

    af(x) represent the graph of f(x) is enlarged a times of the oringinal to the y-axis.
