"Web6 okt. 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). " - If a 0 does the graph open up or down
