domain of f(x)=sqrt(15-2x)+sqrt(2x+5)

domain

f (x) = 15 - 2 x + 2 x + 5

- \frac{5}{2} \leq x \leq \frac{15}{2}

Solution steps

Find non-negative values for radicals:

- \frac{5}{2} \leq x \leq \frac{15}{2}

The function domain

- \frac{5}{2} \leq x \leq \frac{15}{2}

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

f (x) = \frac{( 2 x ^{2} - 6 x + 4 )}{- 3 x - 5}

1.5 - 3 x

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

y = \frac{1}{x - 3}
