domain of f(x)=sqrt(5-4x+7x)

domain

f (x) = 5 - 4 x + 7 x

x \geq - \frac{5}{3}

Interval Notation

[- \frac{5}{3}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - \frac{5}{3}

The function domain

x \geq - \frac{5}{3}

f (x) = \frac{- 5 x - 3}{4 x - 2}

f (x) = \frac{x ^{2} - 9}{x ^{2} + 4 x + 3}

\frac{7 x}{4 x - 1}

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

f (x) = - 8 x - 4

What is the domain of f(x)=sqrt(5-4x+7x) ?
The domain of f(x)=sqrt(5-4x+7x) is x>=-5/3
