range of f(x)=sqrt(4-x)+1

range

f (x) = 4 - x + 1

f (x) \geq 1

Interval Notation

[1, \infty)

Solution steps

The range of an radical function of the form

c a x + b + k

f (x) \geq k

k = 1

f (x) \geq 1

f (x) = x - 2 + 3

f (x) = x^{2} + 2 x - 15

3 - x

(- 5, 6), (- 3, - 1)

f (x) = 5 x^{4} + 8 x^{3} + 2 x^{2}

What is the range of f(x)=sqrt(4-x)+1 ?
The range of f(x)=sqrt(4-x)+1 is f(x)>= 1
