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

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

7

Solution steps

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

Plug in the value

x = 1

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

Simplify

= 7

\frac{d ^{2} y}{d t ^{2}} - 5 \frac{d y}{d t} + 6 y = 0

\frac{\partial}{\partial x} (ln (x^{5} + y^{5}))

e^{- 1 (t + 1)}

\int e^{0.5 x} d x

\int e^{- 2 x + 3} d x
