Write a small function which takes as inputs; a number a and a function g(x), and returns (a, g(a)). Note that printing is not the same as returning a value. Use the function g(x) = 2x 2 and a = 4 to test your function.
So my function right now looks like this.
function [a g(x)] = mysmallfunction(x)
a = x;
g(x) = 2*x.^2;
And I'm calling it like this:
[a g(x)] = mysmallfunction(4)
I get the error "Undefined function or variable 'mysmallfunction'."
But also I'm using a specific equation in 2x^2. How do I make it work for any equation.
