Graphs of f(x) + 1 and f(x) - 2 demonstrating vertical translations of a quadratic function.
Two graphs showing quadratic functions f(x) + 1 and f(x) - 2, illustrating vertical translations of the parabola. The left graph shows f(x) + 1 with a table of values and a translation by vector (0,1). The right graph shows f(x) - 2 with a table of values and a translation by vector (0,-2).
