Question 304229
{{{f(x)=1-x^2}}}
{{{f(x+h)-((f(x))/h)}}}
{{{f(x)+f(h)-((f(x))/h)}}}
{{{(1-x^2)+f(h)-((1-x^2)/h)}}}
{{{(h/h)(1-x^2+f(h))-((1-x^2)/h)}}}
{{{((1h-hx^2+f(h^2))/h)-((1-x^2)/h)}}}
{{{(1h-(h+1)x^2+fh^2+1)/h}}}

there are 3 variables, there arent any numeric values so this is as far as u can solve it
