Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone, anywhere. Then we can add a slider k here, and this is just allowing us to f of negative 3. A parabola labeled f and graph g are on an x y coordinate plane. So if I were to take over here at zero, zero. Geometry swoops in as we translate, reflect, and dilate the graphs, working back and forth between the geometric and algebraic forms. absolute value function. Keep going! Identifying function transformations (video) | Khan Academy we need to get to 6. This is true for 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).
