limit as x approaches-2 of 3x^2+5x-1

x \to - 2 lim (3 x^{2} + 5 x - 1)

1

Solution steps

x \to - 2 lim (3 x^{2} + 5 x - 1)

Plug in the value

x = - 2

= 3 (- 2)^{2} + 5 (- 2) - 1

Simplify

3 (- 2)^{2} + 5 (- 2) - 1 : 1

= 1

\int \frac{t}{( t ^{2} + 1 ) ^{\frac{5}{2}}} d t

\int \frac{1}{16 x ^{2} + 7} d x

\frac{13}{x}

\frac{d}{d t} (e^{7 t s i n (2 t)})

x \to 0 lim (sin (\frac{1}{x}))
