Sagot :

The limit of the expression as x approaches -3 is -24

How to determine the limit of the expression?

The expression is given as:

[tex]x^3 + 3x^2 + 4x - 12[/tex]

As x approaches -3.

The limit expression becomes

[tex]\lim_{x \to -3} x^3 + 3x^2 + 4x - 12[/tex]

Substitute -3 for x in the expression

[tex]\lim_{x \to -3} (-3)^3 + 3(-3)^2 - 4*3 - 12[/tex]
