domain of f(x)=-2sqrt(49x+49)

domain

f (x) = - 2 49 x + 49

x \geq - 1

Interval Notation

[- 1, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 1

The function domain

x \geq - 1

\frac{\frac{1}{x}}{x ^{2} - 4}

f (x) = 2 - 5 x

y = - 5 + 4 x

f (x) = \frac{x}{x + 4}

f (x) = (x - 3)^{2} + 1
