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

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

- 2

Solution steps

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

Plug in the value

x = - \frac{1}{2}

= 2 (- \frac{1}{2})^{2} + 3 (- \frac{1}{2}) - 1

Simplify

2 (- \frac{1}{2})^{2} + 3 (- \frac{1}{2}) - 1 : - 2

= - 2

x \to - 8 + lim (\frac{1}{x + 8})

\frac{\partial}{\partial y} (sin (x + y))

y = x^{2} + 10 x + 21

\int \frac{9}{81 - 9 x ^{2}} d x

\frac{d}{d x} (6 y cos (x))
