limit as x approaches 2-of 4x-5

解答

x \to 2 - lim (4 x - 5)

3

求解步骤

x \to 2 - lim (4 x - 5)

代入值

x = 2

= 4 \cdot 2 - 5

化简

= 3

d er i v a t i v e y = 2 e^{x} - e^{x + 1} + e^{\frac{2}{3}} - 5 π^{2}

l a pl a ce t r an s f or m 4 t^{2} - 5 sin (3 t)

\int_{0}^{5} \frac{3 x - 4}{x + 1} d x

x \to 0 - lim (\frac{1}{x ^{2}} - \frac{1}{x})

\int_{1}^{3} e^{x^{2}} d x
