Plz, help me thank you I really need it :)

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)-144x+360 what am i doing wrong?

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

Find the domain of the following expression: 1/(√x)-2
