WebWhat is the equation for a quadratic function that passes through the points (1,2), (2,1), and (3,0)? Solution: By using the point-slope form of a line, we can create two equations: y - 2 = m(x - 1) and y - 1 = m(x - 2) Solving for m and substituting into the second equation, we have: y - 1 = (y - 2)(x - 2)/(x - 1) Expanding, we have: y - 1 = y - 2x + 4 Solving for y, … WebWe have already looked at how to expand brackets in algebra.
