The degree is even (4) and the leading coefficient is negative (3), so the end behavior is, \[\text{as }x{\rightarrow}{\infty}, \; f(x){\rightarrow}{\infty} \nonumber\], \[\text{as } x{\rightarrow}{\infty}, \; f(x){\rightarrow}{\infty} \nonumber\]. Short story taking place on a toroidal planet or moon involving flying. Figure \(\PageIndex{4}\) shows the end behavior of power functions in the form \(f(x)=kx^n\) where \(n\) is a non-negative integer depending on the power and the constant. For the function \(g(t)\), the highest power of \(t\) is 5, so the degree is 5. Given the function \(f(x)=4x(x+3)(x4)\), determine the local behavior. The leading term is the term containing that degree, \(p^3\); the leading coefficient is the coefficient of that term, 1. A turning point of a graph is a point at which the graph changes direction from increasing to decreasing or decreasing to increasing. I have learned more from this app than I have from any of my college professors (believe it or not). The \(x\)-intercepts are \((0,0)\),\((3,0)\), and \((4,0)\). For the function \(f(x)\), the highest power of \(x\) is 3, so the degree is 3.
