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

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

256

Solution steps

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

Plug in the value

x = 3

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

Simplify

3 \cdot 3^{4} + 2 \cdot 3^{2} - 5 : 256

= 256

f (x) = (- 3 x^{2} + 2 x + 4)^{12}

\frac{d}{d x} (1 - 169 x^{2} arccos (13 x))

\frac{9 x ^{2} + 9 x}{8 x}

\int \frac{1}{2 - t} + \frac{1}{2 + t} d t

\int_{- \infty}^{4} e^{- x} d x
