domain of f(x)=sqrt(7x+9)

domain

f (x) = 7 x + 9

x \geq - \frac{9}{7}

Interval Notation

[- \frac{9}{7}, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - \frac{9}{7}

The function domain

x \geq - \frac{9}{7}

f (x) = \frac{x ^{7} - 4 x ^{6} - 16 x ^{5} + 64 x ^{4}}{x}

f (x) = lo g_{10} (2 - x) + x - 3

g (x) = ln (x + 3)

x^{3} - 7 x - 6

\frac{x ^{3}}{3 - x}

What is the domain of f(x)=sqrt(7x+9) ?
The domain of f(x)=sqrt(7x+9) is x>=-9/7
