domain of f(x)=x^2-2x,x>= 1

domain

f (x) = x^{2} - 2 x, x \geq 1

x \geq 1

Interval Notation

Solution steps

Set the domain to the given interval

x \geq 1

The function has no undefined points nor domain constraints. Therefore, the domain is

x \geq 1

5 x^{2} + 4

f (x) = \frac{7 x + 1}{2 x ^{2} + 3 x}

2 x^{2} - 24 x + 64

f (x) = 3 - (\frac{13}{x ^{2} + 5})

f (x) = \frac{8 - x}{x + 3}
