domain of y=x^2+3

domain

y = x^{2} + 3

- \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

in v erse - 6 x - 7

cr i t i c a l 14 cos (θ) + 7 sin^{2} (θ)

s l o p e 3 x + 5 y = - 5

r an g e f (x) = x^{2} - 8 x

r an g e x^{2} - 16
