Does the maximum value problem of quadratic function contain absolute value? F (x) = the square of X + the absolute value of x-2-1 to find the minimum value of the function,

Does the maximum value problem of quadratic function contain absolute value? F (x) = the square of X + the absolute value of x-2-1 to find the minimum value of the function,

It is suggested that when the absolute value is positive or negative, the value of X and f (x) should be determined, and then the minimum value should be compared
