Which of the following graphs represents the function f(x) = 2^x

The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.

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?
