domain of f(x)=(-sqrt(7-2x))/(x^2+x+1)

domain

f (x) = \frac{- 7 - 2 x}{x ^{2} + x + 1}

x \leq \frac{7}{2}

Interval Notation

(- \infty, \frac{7}{2}]

Solution steps

Find non-negative values for radicals:

x \leq \frac{7}{2}

The function domain

x \leq \frac{7}{2}

y = - 1 - 3

(- 7, - 2), (2, 7)

tan^{2} (x)

f (x) = \frac{( x + 1 )}{( 2 x + 1 )}

f (x) = (x - 2)^{2} (x - 4)^{2}
