Read restricted graphs and horizontal level sets
The function has rule
\[f(x)=\left(x+1\right)^{4}\]
Its stated domain is \((-3,1]\). The graph is restricted to the stated interval; the plotting window is only the window used for the display
The plotting window is x from -4 to 2 and y from -2 to 18
The exact boundary points are (-3,16) and (1,16). The internal data are (-1,0)
The x-intercept is (-1,0); the y-intercept is (0,1)
