limit as x approaches 4 of (4-x)/(x-4)

x \to 4 lim (\frac{4 - x}{x - 4})

- 1

Solution steps

x \to 4 lim (\frac{4 - x}{x - 4})

\frac{4 - x}{x - 4} = - 1

= x \to 4 lim (- 1)

x \to a lim c = c

= - 1

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

\int_{- 4}^{0} f (x) d x

n = 1 \sum \infty cos^{n} (1)

n = 0 \sum \infty (0.02)^{n}

\int 5 e^{x} d x
