limit as x approaches-4 of x^3-4x^2+7

x \to - 4 lim (x^{3} - 4 x^{2} + 7)

- 121

Solution steps

x \to - 4 lim (x^{3} - 4 x^{2} + 7)

Plug in the value

x = - 4

= (- 4)^{3} - 4 (- 4)^{2} + 7

Simplify

(- 4)^{3} - 4 (- 4)^{2} + 7 : - 121

= - 121

3 y^{^{''}} - 12 y^{^{'}} + 9 y = 3 sin (4 x)

x \to 1 lim (\frac{x}{( x - 1 ) ^{2}})

y^{^{'''}} - y^{^{'}} = 2 sin (3 x)

\int \frac{3}{64} x^{2} d x

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