WebWe can use what we've found above to sketch a graph of y=f (x) y = f (x). Let's start with end behavior: As x\rightarrow +\infty x → +∞ , f (x)\rightarrow +\infty f (x) → +∞ . As x\rightarrow -\infty x → −∞ , f (x)\rightarrow -\infty f (x) → −∞ . This means that in the "ends," the graph will look like the graph of y=x^3 y = x3.
WebMay 16, 2024 · If we consider a general quadratic equation: ax^2 + bx+ c = 0 And suppose that we denote roots by alpha and beta, then x=alpha, beta => (x-alpha)(x-beta) = 0 :. x^2 - (alpha+beta)x+alpha beta = 0 Equivalently we can write as :. x^2 - ("sum of roots")x+("product of roots") = 0 And comparing these identical equations we can … WebDec 21, 2024 · The fundamental theorem of algebra can help you find imaginary roots.
