limit as x approaches-1 of (x+4)/(2x+1)

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

- 3

Solution steps

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

Plug in the value

x = - 1

= \frac{- 1 + 4}{2 ( - 1 ) + 1}

Simplify

\frac{- 1 + 4}{2 ( - 1 ) + 1} : - 3

= - 3

x \to 0 lim (\frac{∣ x ∣ - x}{x})

\frac{d}{d x} (\frac{1}{tan ( x )})

\int \frac{cos ( x )}{4 - sin ^{2} ( x )} d x

\int (sec^{2} (x) - 7) d x

f (x) = \frac{3 x}{x - 2}
