Question

The function f(x) = x^2- 4x + 3 has a relative minimum located at which of the following x values?

Answer 1

Idk I really don’t do that work in my class but I wish u do Good✅

Answer 2

Given a quadratic equation $y=ax^2+bx+c$, the x coordinate of the minumum/maximum is given by

$x=-\dfrac{b}{2a}$

So, in your case, the x coordinate of the minimum is

$x=-\dfrac{-4}{2}=2$
