👉 In mathematics, a minimizer of a function is an input value that produces the smallest possible output value. In other words, it's the point at which the function attains its minimum value. For example, consider the function f(x) = x^2 - 4x + 3. To find the minimum value, we need to set f'(x) equal to zero and solve for x: f'(x) = dx/dx = 2x - 4 Setting
