Data that will model a polynomial function

Web9. I generated some data from a 4th degree polynomial and wanted to create a regression model in Keras to fit this polynomial. The problem is that predictions after fitting seem to be basically linear. Since this is my first time working with neural nets I assume I made a very trivial and stupid mistake. Here is my code: WebPolynomial Functions: A polynomial function is one that has the form, $$ y = a_{n}x^{n} + a_{n-1}x^{n-1} + ... + a_{2}x^{2} + a_{1}x + a_{0} \, , $$ with \(n\) denoting a non …
