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

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

- 75

Solution steps

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

Plug in the value

x = - 4

= (2 (- 4) + 3) ((- 4)^{2} - 1)

Simplify

(2 (- 4) + 3) ((- 4)^{2} - 1) : - 75

= - 75

\int \frac{2}{( x + 2 ) ^{2} x ^{2} + 4 x + 13} d x

\int e^{2 y^{2}} d y

x \to 1 lim (f (x))

\int 60 sec^{4} (x) d x

6 t^{2} + 3 t + 7
