Linear Algebra Examples

$(1.3 x^{3} + 4.6 x^{2} - 3.2 x) - (- 4.8 x^{3} - 4.9 x^{2} + 76)$

Step 1

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:

$(- \infty, \infty)$

Set-Builder Notation:
