limit as x approaches 1 of 2x^3-4x^2+x+8

x \to 1 lim (2 x^{3} - 4 x^{2} + x + 8)

7

Solution steps

x \to 1 lim (2 x^{3} - 4 x^{2} + x + 8)

Plug in the value

x = 1

= 2 \cdot 1^{3} - 4 \cdot 1^{2} + 1 + 8

Simplify

= 7

9 x + 4

y^{^{''}} + 2 y^{^{'}} + 5 y = 5 sin (2 t)

y = (e^{x} + 4)^{3}

y^{^{''}} - 3 y^{^{'}} + 2 y = e^{x} + 2 e^{3 x}

\frac{d}{d z} (y z)
