domain of 7x+1

domain

7 x + 1

- \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

r an g e 6 x^{3} + 8 x^{2}

s im pl i f y (- 1.2) (- 7)

r an g e ∣ x - 5 ∣

in v erse f (x) = 7 x - 14

d o main f (x) = 3 x^{3} + \frac{x}{2} - 3 x - 3
