limit as x approaches 1 of-2x^2+5x+4

x \to 1 lim (- 2 x^{2} + 5 x + 4)

7

Solution steps

x \to 1 lim (- 2 x^{2} + 5 x + 4)

Plug in the value

x = 1

= - 2 \cdot 1^{2} + 5 \cdot 1 + 4

Simplify

= 7

\frac{d}{d x} (\frac{x ^{2}}{x ^{2} + y ^{2}})

\frac{d}{d x} (sin^{\frac{1}{2}} (x))

\frac{d}{d x} (10 x + 9 x^{2} + 3 y)

\frac{d y}{d x}, y = arcsin (2 x + 1)

e^{\frac{t ^{2}}{2}}
