WebQuadratic functions are usually the first we encounter that have curved or nonlinear graphs. The graph of a quadratic function is a specific kind of curve called a parabola, a sort of U-shaped figure. *.

WebNov 1, 2024 · The graph is the basic quadratic function shifted 2 units to the right, so g(x) = f(x − 2) Notice how we must input the value x = 2 to get the output value y = 0; the x -values must be 2 units larger because of the shift to the right by 2 units. We can then use the definition of the f(x) function to write a formula for g(x) by evaluating f(x − 2).
