limit as x approaches 3 of 3x^3-5x^2+x-8

x \to 3 lim (3 x^{3} - 5 x^{2} + x - 8)

31

Solution steps

x \to 3 lim (3 x^{3} - 5 x^{2} + x - 8)

Plug in the value

x = 3

= 3 \cdot 3^{3} - 5 \cdot 3^{2} + 3 - 8

Simplify

3 \cdot 3^{3} - 5 \cdot 3^{2} + 3 - 8 : 31

= 31

\frac{d y}{d x} = \frac{( x y ) ^{2}}{8} + y^{2}

\int \frac{1}{x ^{2} + 6 x + 5} d x

x \to 4 + lim (\frac{1}{x ^{2} - 16})

\frac{d ^{2}}{d x ^{2}} (\frac{x}{x ^{2} + 4})

\int \frac{64 x ^{2} - 49}{x ^{3}} d x
