domain of f(x)=sqrt(2+7x)

domain

f (x) = 2 + 7 x

x \geq - \frac{2}{7}

Interval Notation

Solution steps

Find non-negative values for radicals:

x \geq - \frac{2}{7}

The function domain

x \geq - \frac{2}{7}

f (x) = \frac{5}{2} x + 8

f (x) = 2 cos (x)

y = \frac{3}{x + 2}

f (x) = 1

\frac{x x}{2 x ^{2} - 5}

What is the domain of f(x)=sqrt(2+7x) ?
