limit as x approaches 4 of 4x^2+5x+1

x \to 4 lim (4 x^{2} + 5 x + 1)

85

Solution steps

x \to 4 lim (4 x^{2} + 5 x + 1)

Plug in the value

x = 4

= 4 \cdot 4^{2} + 5 \cdot 4 + 1

Simplify

4 \cdot 4^{2} + 5 \cdot 4 + 1 : 85

= 85

\frac{d}{d x} (3 x + 3)

x \to 0 lim (\frac{x}{sin ( \frac{x}{4} )})

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

y^{^{'}} - \frac{9}{x} y = \frac{y ^{4}}{x ^{13}}, y (1) = 1

\frac{d x}{d t} - 4 x = cos (3 t), x (0) = - 1
