A cubic function is a polynomial function of degree 3 and is of the form f (x) = ax 3 + bx 2 + cx + d, where a, b, c, and d are real numbers and a ≠ 0. The basic cubic function (which is also known as the parent cube function) is f (x) = x 3. Since a cubic function involves an odd degree polynomial, it has at least one … See more Since a cubic function y = f(x) is a polynomial function, it is defined for all real values of x and hence its domain is the set of all real numbers … See more The asymptotes always correspond to the values that are excluded from the domain and range. Since both the domain and range of a cubic function is the set of all real numbers, no values are excluded from either the domain or … See more A cubic function always has exactly one y-intercept. To find the y-intercept of a cubic function, we just substitute x = 0 and solve for y-value. Example: To find the y-intercept of f(x) = x3 - … See more The x-intercepts of a function are also known as roots (or) zeros. As the degree of a cubic function is 3, it can have a maximum of 3 roots. Since complex roots of any function … See more WebThe two known roots have sum 2, so the missing root must be − 2. If the leading term of the polynomial has coefficient 1, then the product of its roots gives the free term. Your polynomial has real coefficients; if 1 − 2 i is a root, then so is 1 + 2 i. Thus, we arrive to 10 = ( 1 − 2 i) ( 1 + 2 i) a, where a is the real root.
