2. Suppose you orient a coordinate grid with the bottom of one leg of the arch at theorigin and the rest of the arch lying in the first quadrant so that the other leg isalso on the x-axis. Sketch the arch in the first quadrant below and label as manycoordinates as you can on the arch.
23. Using the general form of a quadratic function, y = a ⋅ x + b ⋅ x + c and the threecoordinates labeled above, write a system of three equations to solve for the threeunknowns, a,b and c.HINT: You will get c directly from one of the equations. Substitute this valueinto the other two. Use one of the other equations to find an equation for b interms of a, and substitute this value for b into the last equation and solve for a.You now have numerical values for a and c use these to solve for b.
