Question

A quadratic function f, of, xf(x) is hidden from view. You must find the xx-intercept(s) of f, of, xf(x) and write the answer(s) in the form left parenthesis, x, comma, y, right parenthesis(x,y). Choose the form of the quadratic function f, of, xf(x) that you would like to see in order to answer the question most efficiently.

Answer

Answer 1

I choose the factored (intercept) form: f(x) = a(x − r1)(x − r2).

Reason: the x-intercepts are immediately r1 and r2, so the answers are (r1, 0) and (r2, 0).

Show the quadratic in that form (give a, r1, r2) and I will list the x-intercept(s). If you prefer a different form, say which (standard or vertex).
