Given f(x) = x2 - 10x + 22, what is the domain of f

Polynomials have the domain of all Reals.   Plugging any Real number into the equation will give you a value. Domain = {x|x∈R} Step-by-step explanation:The range is dependent on the curve itself.  The axis of symmetry for this function isx = -b/2a = -1(-10)/2(1) = 10/2 = 5 The vertex is F(5) = (5)2 + (-10)(5) + 21 = 21 -50 + 21 = -8Since the leading coefficient is positive, the parabola opens up and the vertex (5,-8) is a local minimum.  It turns out to be an absolute minimum too so the Range = {x|x∈R, x≥-8}Thank yousunshinemadison101

The answer would be d i think but i’m for sure it is not a and c
