limit as x approaches 4 of 2x^2-3x+1

x \to 4 lim (2 x^{2} - 3 x + 1)

21

Solution steps

x \to 4 lim (2 x^{2} - 3 x + 1)

Plug in the value

x = 4

= 2 \cdot 4^{2} - 3 \cdot 4 + 1

Simplify

2 \cdot 4^{2} - 3 \cdot 4 + 1 : 21

= 21

x \to \infty lim (\frac{6}{x} - 8)

x \to \infty lim (0.8 x)

x \to 0 lim ((x^{3} - 3) (x + 2))

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

x \to 2 lim (3 x^{2} \cdot 2 x)
