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

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

53

Solution steps

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

Plug in the value

x = 4

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

Simplify

= 53

\frac{d}{d x} (\frac{0.6 e ^{x}}{cos ( x )})

x + 3

\int \frac{7}{( 7 ^{2} + x ^{2} ) ^{\frac{3}{2}}} d x

\frac{d}{d x} (\frac{5}{x + 2})

x \to 0 lim (x [\frac{1}{x}])
