Answer variants:
\(\frac{3 - x}{3} - 1\)
\(4x^2 + 8x + 3\)
\(x^2 - 12x + 36\)
\(\frac{9 - x}{3}\)
\(x^2 - 6\)
\(4x^2\)
\(\frac{8}{x^2} - 1\)
\(x - 1\)
\(\frac{2}{2x^2 - 1}\)
Using the functions \(f\) and \(g\) given below, find \(f \circ g\) and \(g \circ f\). Check whether \(f \circ g = g \circ f\).
 
\(f(x) = 4x^2 - 1\), \(g(x) = 1 + x\)
 
\(f \circ g\) \(=\)
 
\(g \circ f\) \(=\)
 
So, .
