The vertex of a quadratic equation is the maximum or minimum point on the equation's parabola. ... To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
What does a quartic function look like?
A quartic function is a fourth-degree polynomial: a function which has, as its highest order term, a variable raised to the fourth power. It can be written as: f(x) = a4 x4 + a3 x3 + a2 x2 +a1 x + a0.
What makes a function quartic?
In mathematics, a quartic function, is a function of the form where a is nonzero, which is defined by a polynomial of degree four, called quartic polynomial. ... The degree four is the highest degree such that every polynomial equation can be solved by radicals.
