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

range

f (x) = x - 4

f (x) \geq - 4

Interval Notation

[- 4, \infty)

Solution steps

The range of an radical function of the form

c a x + b + k

f (x) \geq k

k = - 4

f (x) \geq - 4

f (x) = 6 - 5 x^{2}

x 4 - x^{2}

f (x) = (t^{2} - 36)^{\frac{1}{3}}

\frac{7}{( x - 4 ) ^{3}}

f (x) = x^{7}
