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

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

21

Solution steps

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

Plug in the value

x = 2

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

Simplify

= 21

x \to 0 lim (\frac{tan ( \frac{x}{2} )}{x})

x \to 0 lim (- tan (x))

x \to \frac{3 π}{4} - lim (2 sec (x))

x \to 0 lim (\frac{3 ^{x} - 1}{4 x})

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