The domain of this function is all real numbers since it is a parabola.

D = {x | x ∈ R }

Since the vertex is at (-3/8 , -25/-16), and a (4) is positive,

Its range is greater than or equal to -25/16.

R = {y ∈ R | y ≥ -25/16 }

D = {x | x ∈ R }

Since the vertex is at (-3/8 , -25/-16), and a (4) is positive,
