limit as x approaches 4 of x^2-5x+7x^3

x \to 4 lim (x^{2} - 5 x + 7 x^{3})

444

Solution steps

x \to 4 lim (x^{2} - 5 x + 7 x^{3})

Plug in the value

x = 4

= 4^{2} - 5 \cdot 4 + 7 \cdot 4^{3}

Simplify

4^{2} - 5 \cdot 4 + 7 \cdot 4^{3} : 444

= 444

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

\int \frac{( u ^{2} ) ^{22}}{1 + ( u ^{2} ) ^{22}} d (u^{2})^{2}

x^{6} + y^{5} x^{7} + 3 y^{^{'}} = 0, y (0) = 0

\frac{d x}{d y} = 2 x - 5 x + 1

\int_{0}^{\infty} 2 e^{- x} d x
