find x value from 3 different value of formula

Answer 1

[Walter Roberson]

Example

part1 = @(x) (x < 2).*(4*sqrt(x) + 2)

part1 = function_handle with value:
    @(x)(x<2).*(4*sqrt(x)+2)

part2 = @(x) (x >= 2 & x <= 5).*(3*x - 1)

part2 = function_handle with value:
    @(x)(x>=2&x<=5).*(3*x-1)

part3 = @(x) (x > 5) .* 5./x;
y = @(x) part1(x) + part2(x) + part3(x);
fplot(y, [0 10])
