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

5 x^{4} - x^{5}

\frac{e ^{x - 3}}{x - 2}

9 + (4 + x)^{\frac{1}{2}}

g (x) = - \frac{1}{3} - x - 2 - 4

f (x) = 1 + \frac{9 x - 70}{x ^{2} - 15 x + 56}
