Decimal representation of rational numbers. When x = -1, k - x^2 = x^2 + x. k - (-1)^2 = (-1)^2 + (-1) k - 1 = 1 - 1. k - 1 = 0. k = 1. Improve this answer. Then graph f(x). Alternatively, if you can define your piecewise functions to be undefined outside the interval of support, then Solve can be used directly: pw1 = Piecewise[{{0.524324 + 0.0376478 x, 0.639464 <= x <= 0.839322}}, Undefined]; pw2 = Piecewise[{{-0.506432 + 1.48068 x, 0.658914 <= x <= 0.77085}}, Undefined]; Solve[pw1 == pw2, x] (* {{x -> 0.714299}} *) ï»¿ Share. Note that this kind of piecewise expression is not compatible with any of the minimizers in the Optimization Toolbox, all of which require continuous first derivatives for the expression. This is done because a piecewise function acts differently at different sections of the number line based on the x or input value. Sum of all three digit numbers divisible by 7.
