limit as x approaches-infinity of-2x-1

x \to - \infty lim (- 2 x - 1)

\infty

Solution steps

x \to - \infty lim (- 2 x - 1)

Apply Infinity Property:

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

n is odd

a = - 2, n = 1

= \infty

\int 25 - 4 x^{2} d x

y = 2 sin (x), at x = \frac{π}{4}

\int sec^{3} (x) tan^{2} (x) d x

x \to 2 + lim (4)

y = 3 8 x^{2}
