If y approaches positive infinity as x increases, as you go to the right on the graph, the line goes upwards forever and doesn't stop. Solving each factor gives me: x + 5 = 0 x = 5 x + 2 = 0 x = 2 Together, this gives us, [latex]f\left(x\right)=a\left(x+3\right){\left(x - 2\right)}^{2}\left(x - 5\right)[/latex]. There are many different types of mathematical questions, from simple addition and subtraction to more complex calculus. If we divided x+2 by x, now we have x+(2/x), which has an asymptote at 0. A polynomial labeled y equals f of x is graphed on an x y coordinate plane. The best app for solving math problems! Select one: But what about polynomials that are not monomials? thanks in advance!!
