range of f(x)=sqrt(x-7)

range

f (x) = x - 7

f (x) \geq 0

Interval Notation

[0, \infty)

Solution steps

The range of an radical function of the form

c a x + b + k

f (x) \geq k

k = 0

f (x) \geq 0

f (x) = 3 tan (2 x)

f (x) = x^{3} - 3 x + 6

f (x) = x^{3} + 17 x^{2} - 80 x + 100

\frac{2 x}{5 x - 6}

f (x) = x^{3} + 4
