limit as x approaches-1 of sqrt(2x^2+3)

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

5

Decimal Notation

2.23606 \dots

Solution steps

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

Plug in the value

x = - 1

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

Simplify

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

= 5

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

y^{^{''}} + y^{^{'}} - 2 y = 4 sin (2 x)

\int e^{- 0.89 x} d x

\frac{\partial}{\partial y} (- y cos (x))

\frac{s + 1}{( s + 1 ) ( s ^{2} + 2 )}
