domain of f(x)=4-sqrt(2x-5)

domain

f (x) = 4 - 2 x - 5

x \geq \frac{5}{2}

Interval Notation

[\frac{5}{2}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq \frac{5}{2}

The function domain

x \geq \frac{5}{2}

f (x) = \frac{x}{( x - 4 ) ( x + 2 )}

f (x) = 7 x^{2} + 7 x + 9

- 5 sin (2 π x + 5)

y = - x

\frac{x ^{3}}{3} + x^{2} - 8 x + 20

What is the domain of f(x)=4-sqrt(2x-5) ?
The domain of f(x)=4-sqrt(2x-5) is x>= 5/2
