limit as x approaches 2 of 4x^3-3x-5

x \to 2 lim (4 x^{3} - 3 x - 5)

21

Solution steps

x \to 2 lim (4 x^{3} - 3 x - 5)

Plug in the value

x = 2

= 4 \cdot 2^{3} - 3 \cdot 2 - 5

Simplify

4 \cdot 2^{3} - 3 \cdot 2 - 5 : 21

= 21

x \to 0 lim ((x + 2) \cdot e^{\frac{1}{x}})

x \to 0 lim (cos (x) sec (x))

x \to 4 + lim (3 x^{2} - 9)

x \to 0 + lim ((a x)^{b x})

x \to 0 lim (x \cdot sin (\frac{2}{x}))
