Cubic Function

Cubic Function


  • In mathematics, a cubic function is a polynomial equation in which the highest occurring power in the unknown is the third power.

  • The standard form of a cubic equation is: ax3 + bx2 + cx +d=0.

  • The cubic function equation is: f(x) = ax3 + bx2 + cx + d.

  • The factored form of the cubic equation is: g(x)=a(x-p)(x-q)(x-r)

  • Example:

f(x)= x3+2 (Green Line)

f(x)= x3+5 (Blue Line)

f(x)= x3+0 (Pink Line)



f(x)= x3-1 (Grey Line)

f(x)= x3-3 (Purple Line)


  • A cubic equation has no exponent larger than 3.
