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

domain

f (x) = x + 7 - x

0 \leq x \leq 7

Interval Notation

[0, 7]

Solution steps

Find non-negative values for radicals:

0 \leq x \leq 7

The function domain

0 \leq x \leq 7

6 x^{2} - 54 x + 120

f (x) = \frac{1}{2 x + 3}

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

y = 7 (x + 3)^{2} - 1

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

What is the domain of f(x)=sqrt(x)+sqrt(7-x) ?
The domain of f(x)=sqrt(x)+sqrt(7-x) is 0<= x<= 7
