The graph of f(x)=3x (red) is increasing. the graph of f(x) =-3x + 9 (blue) is decreasing.Increasing functions travel upwards from left to right; as x increases, y decreases. With decreasing functions, as you move from left to right, the graph goes downward. In other words, as...
They are called “symmetric” not because their graph showssymmetry, but because they remain the same if you permute their roots. As far as graphing, the graph of any symmetric polynomial would look exactly the same no matter which variables you switch around. If the graph changes, then the ...
