HELP PLEASE PLEASE PLEASE! Use matrix manipulation to solve for a, b, and c. Set up a matrix equation for AX = B based on the system ofequations you derived in part B where X is a matrix of the variables a, b, and c. Then, use Gauss-Jordan elimination to find the inverse of A. Finally, use your results to write the equation of the parabola. Show your work and final equation in the space provided.
