range of f(x)=sqrt(-x)+5

range

f (x) = - x + 5

f (x) \geq 5

Interval Notation

[5, \infty)

Solution steps

The range of an radical function of the form

c a x + b + k

f (x) \geq k

k = 5

f (x) \geq 5

s l o p e in t erce pt y - 1 = 9 (x - 1)

d o main f (x) = 5 ln (x)

in f l ec t i o n \frac{x}{x ^{2} - 4}

r an g e y = 2 x^{2} + 20 x + 53

d o main x ∣ x ∣
