Piecewise Function

Write a MATLAB function (not script) that takes an input number, x, and returns an output number, y, that will be of the following form:

y= e^x when x>0

y= e^(-x) when-1 x 0

y= -e*x when x < -1

Note that the built in function exp(n) takes the constant e to any power n, and that you can get the constant e by writing exp(1).

Your Function

function y = piecewise(x)

y = x;

end

Code to call your function

y = piecewise(0.5)

y = piecewise(-1.5)

y = piecewise(2)
