domain of y=sqrt(4/9 x-1)

domain

y = \frac{4}{9} x - 1

x \geq \frac{9}{4}

Interval Notation

[\frac{9}{4}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq \frac{9}{4}

The function domain

x \geq \frac{9}{4}

f (x) = - 3 x + 6

f (x) = - 3 x + 3

g (x) = \frac{5 x + 3 - x ^{2}}{3}

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

2 - 4 x
