All polynomials are continuous, so the limit can be evaluated by direct substitution:
[tex]\displaystyle \lim_{x\to-3} (x^3+3x^2+4x-12) = (-3)^3+3(-3)^2+4(-3)-12 = \boxed{-24}[/tex]
The Limit of (x cubed + 3 x squared + 4 x minus 12) as x approaches negative 3 is -24.
Polynomials are those algebraic expressions that consist of variables, coefficients, and constants. The standard form of polynomials has mathematical operations such as addition, subtraction, and multiplication.
All polynomials are continuous, so the limit can be evaluated by direct substitution:
