domain of f(x)=-x+4x

domain

f (x) = - x + 4 x

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

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

- \infty < x < \infty

f (x) = - 4 x - 51

f (x) = 9 x - 8

(x - 5)^{(- \frac{1}{6})}

- 7 x + 3

- 7 x + 7

What is the domain of f(x)=-x+4x ?
The domain of f(x)=-x+4x is -infinity <x<infinity
