Transformations of functions | Algebra 2 | Math | Khan Academy The graph of y=f (x)+k (where k is a real number) is the same as the graph of y=f (x) only it's shifted up (when k>0) or down (when k<0). Parent function: For the two values of that are negative ( -2 and -1 ), replace the 's with the from the absolute value ( 2 and 1, respectively) for those points. Note that if we had instead used g(x) = f(x+3), then g(5) would equal f(8), which may or may not equal 9.

And we see whatever f of to set what k is equal to, so here, k is equal to one, so this is x squared plus one, and notice, we have shifted up, and if we increase the value of k, notice how it shifts the graph up, and as we decrease the value of k, if k is zero, we're back where our vertex is right at the origin, and as we decrease the value of k, it shifts our graph down. 378K views 1 year ago New Precalculus Video Playlist This precalculus video tutorial provides a basic introduction into transformations of functions.

A similar thing happens when we graph y=f(kx), only now the distance from the y-axis changes. In Mathematics II, you started looking at transformations of specific functions.

The graph of y=f(x)+k (where k is a real number) is the same as the graph of y=f(x) only it's shifted up (when k>0) or down (when k<0). Suppose we have a graph of a function f(x) that passes through the point (2, 9), so f(2) = 9.
