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

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

2

Solution steps

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

Plug in the value

x = 1

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

Simplify

= 2

\int 3 e^{x} + 7 sec^{2} (x) d x

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

x \to - 2 lim (x)

\int \frac{x ^{2} + 1}{( x - 9 ) ( x - 8 ) ^{2}} d x
