I need some help using code blocks. We have to obtain a fourth-order polynomial regression. (x = 2.2, 3.1, 4.5, 6.0, 7.3, 8.8). (y=f(x) = 3.2, 9.1, 14.3, 19.0, 25.5, 31.2). With code blocks I have to use numerical methods to solve the linear system equation to find a₀, a₁, a₂, a₃. and a₄. The C-code must contain the following: use of arrays, use of pointers, use of structure, use of union, use of functions, and function calls. Please help me out.
