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

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

53

Solution steps

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

Plug in the value

x = 3

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

Simplify

3^{3} + 3 \cdot 3^{2} - 3 + 2 : 53

= 53

x^{2} - 7, 6 x

\frac{d}{d x} (3 e^{1 - x^{2}})

f (y) = \frac{1}{y ^{2}}

y \frac{d y}{d x} = - x

\int cos^{3} (\frac{x}{2}) sin^{2} (\frac{x}{2}) d x
