I need help, I need to find the value of j, thank you

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?

Which statements regarding efg are true? check all that apply.

The table represents a function. what is f(-2)? a.-3 b. -1 c.1 d.3
