limit as x approaches infinity of x^2-9

x \to \infty lim (x^{2} - 9)

\infty

Solution steps

x \to \infty lim (x^{2} - 9)

Apply Infinity Property:

x \to \pm \infty lim (a x^{n} + \dots + b x + c) = \infty, a > 0,

n is even

a = 1, n = 2

= \infty

(x^{2} - 60) (2 x - 3)

\int \frac{x - 4}{x + 2} d x

\int (2 t + 1) d t

\int \frac{3 x ^{3} - 2 x ^{2} + 2 x - 4}{- x ^{4} - 2 x ^{2}} d x

81 y^{^{''}} + 72 y^{^{'}} + 16 y = 0, y (0) = 2, y^{^{'}} (0) = - 1
