domain of y=sqrt(x+4)+5x^2-2x

domain

y = x + 4 + 5 x^{2} - 2 x

x \geq - 4

Interval Notation

[- 4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 4

The function domain

x \geq - 4

f (x) = x^{4} - 4 x^{3} - 2 x^{2} + 12 x + 9

f (x) = x, x \geq 0

f (x) = \frac{5}{x ^{2} - 3 x - 10}

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

f (y) = - X + 3 + 1
