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

domain

f (x) = 7 - 4 x

x \leq \frac{7}{4}

Interval Notation

(- \infty, \frac{7}{4}]

Solution steps

Find non-negative values for radicals:

x \leq \frac{7}{4}

The function domain

x \leq \frac{7}{4}

- x^{2} + 2 x + 1

f (x) = \frac{x + 4}{x + 5}

f (x) = \frac{x + 1}{x - 5}

sin (\frac{1}{x})

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