limit as x approaches 4 of 2x^2+4x+1

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

49

Solution steps

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

Plug in the value

x = 4

= 2 \cdot 4^{2} + 4 \cdot 4 + 1

Simplify

2 \cdot 4^{2} + 4 \cdot 4 + 1 : 49

= 49

x \to 0 lim (ln (1 - e^{x}))

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

x \to 2 lim (4 x - 3)

x \to 1 lim ((x + 3) (x^{2} + 1))

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