WebCubic Graphs A cubic function is a polynomial of degree three. e.g. y = x 3 + 3x 2 − 2x + 5 Cubic graphs can be drawn by finding the x and y intercepts. Because cubic graphs do not have axes of symmetry the turning points have to be found using calculus. Sketching Cubics Method 1: Factorisation. WebIn this article, we review how to graph quadratic functions. Looking for an introduction to parabolas? Check out this video. Example 1: Vertex form Graph the equation. y=-2 (x+5)^2+4 y = −2(x + 5)2 + 4 This equation is in vertex form. y=\goldD {a} (x-\blueD h)^2+\greenD k y = a(x − h)2 + k
Cubic function - Wikipedia
WebIn general, finding the 𝑥-intercepts of a cubic graph means solving the corresponding equation to find the roots, which is not something we have covered yet. However, in the case of factored cubic equations, we can determine the roots of a factored polynomial by noting that for a product to be equal to 0, one of the factors must be equal to 0.
