    So will it then become y= 3(-1^2/3) -2 OR y=-4^2/3 -2

    because of order of operations, you should first raise the -1 to the exponent and then multiply by 3 and then subtract 2

    so first you do everything in parentheses (which there are none) then exponents then multiplication and division then addition and subtraction
