range of f(x)=sqrt(x)-2

range

f (x) = x - 2

f (x) \geq - 2

Interval Notation

[- 2, \infty)

Solution steps

The range of an radical function of the form

c a x + b + k

f (x) \geq k

k = - 2

f (x) \geq - 2

sy mm e t ry y = - x^{2} + 4 x - 2

d o main y = \frac{2 x}{( x - 2 ) ( x + 1 )}

r an g e f (x) = - x + 2 - 3

r an g e 10 x + 200

in v erse f (x) = - 4 x - 10
