limit as x approaches-2 of 2x^2-8x-3

x \to - 2 lim (2 x^{2} - 8 x - 3)

21

Solution steps

x \to - 2 lim (2 x^{2} - 8 x - 3)

Plug in the value

x = - 2

= 2 (- 2)^{2} - 8 (- 2) - 3

Simplify

2 (- 2)^{2} - 8 (- 2) - 3 : 21

= 21

\int \frac{9 x ^{2} - 8 x + 16}{x ^{3} + 4 x} d x

\int e^{c o s (11 t)} sin (11 t) d t

\frac{d}{d x} (\frac{1}{9})

\int \frac{a + b x ^{4}}{5 a x + b x ^{5}} d x

\frac{d}{d x} (ln (21 x))
