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

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

2

Solution steps

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

Plug in the value

x = 1

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

Simplify

= 2

f (x) = x - 5 3 x

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

10 e^{- 8 (t - 6)}

\frac{d}{d x} (\frac{x + 1}{3})

\int_{1}^{5} \frac{x ^{2} + 3}{6 x - x ^{2}} d x
