domain of f(x)=sqrt(7x+20)

domain

f (x) = 7 x + 20

x \geq - \frac{20}{7}

Interval Notation

[- \frac{20}{7}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - \frac{20}{7}

The function domain

x \geq - \frac{20}{7}

f (x) = 9 x - 7 y = 14

f (x) = 4 (1.5)^{x} - 3

f (x) = - x^{3} + 2 x^{2} + 15 x - 5

f (x) = \frac{56 x + 49}{x ^{2}}

f (x) = \frac{5}{5 x - 16}

What is the domain of f(x)=sqrt(7x+20) ?
The domain of f(x)=sqrt(7x+20) is x>=-20/7
