Let f(t) be a function defined on [-1,7].

Let f(t) be a function defined on [-1,7]. For -1≤t≤0 the graph of f(t) is the upper right quarter of a circle of radius 1 centered at (-1,0); For 0<t<2 the graph of f(t) is the bottom half of a circle of radius 1 centered at (1,0);For 2≤t<4 the graph of f(t) is a straight line with left endpoint (2,1) and slope 3/2; Finally on the interval [4,7], f(t) is continuous but its graph is an unknown curve. Please sketch the graph.
