limit as x approaches 4 of-2x^2+4x-4

x \to 4 lim (- 2 x^{2} + 4 x - 4)

- 20

Solution steps

x \to 4 lim (- 2 x^{2} + 4 x - 4)

Plug in the value

x = 4

= - 2 \cdot 4^{2} + 4 \cdot 4 - 4

Simplify

- 2 \cdot 4^{2} + 4 \cdot 4 - 4 : - 20

= - 20

\int sin (\frac{15}{4}) d θ

ln (\frac{x}{2})

\frac{d y}{d x} (x + 1) + y = ln (x), y (1) = 10

2 x^{2}, (3, 18)

x^{2} y^{^{''}} + 4 x y^{^{'}} + 2 y = \frac{1}{x}
