domain of f(x)=sqrt(-5x+45)

domain

f (x) = - 5 x + 45

x \leq 9

Interval Notation

(- \infty, 9]

Solution steps

Find non-negative values for radicals:

x \leq 9

The function domain

x \leq 9

f (x) = \frac{4 x + 7}{4 x + 8}

\frac{( 1 - ln ( 2 x ) )}{x}

f (x) = 5 x^{2} - 48 x + 27

f (x) = 230 x - x^{2}

\frac{( - 6 x ^{2} )}{( x ^{2} + 1 )}
