domain of f(x)=7-sqrt(9-3x)

domain

f (x) = 7 - 9 - 3 x

x \leq 3

Interval Notation

(- \infty, 3]

Solution steps

Find non-negative values for radicals:

x \leq 3

The function domain

x \leq 3

2 - 3 x

f (x) = \frac{3 - x ^{2} - 7}{x - 4}

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

y = - 2 tan (2 θ) + 1

f (x) = \frac{4 x - 5}{x + 6}
