domain of y=sqrt((7x^2-63)/4)

domain

y = \frac{7 x ^{2} - 63}{4}

x \leq - 3 or x \geq 3

Interval Notation

(- \infty, - 3] \cup [3, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 3 or x \geq 3

The function domain

x \leq - 3 or x \geq 3

x^{2} - y - 2 x + 1 = 0

f (x) = - \frac{7}{2} (5)^{x - 2} + 1

- 2 x (x - 1) (x - 2)

ln (y)

g (x) = lo g_{10} (x - 4)

What is the domain of y=sqrt((7x^2-63)/4) ?
The domain of y=sqrt((7x^2-63)/4) is x<=-3\lor x>= 3
