range of 4sqrt(x-2)-1

range

4 x - 2 - 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) = ln (1 - x)

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

f (x) = e^{x + x^{2}}

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

\frac{8}{x x ^{2} - 4}
