f(x)=4x^2+3x-1
What is the domain and range of this func and solution??

Sagot :

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 }
