limit as x approaches-2 of x^2+2t-1

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

2 t + 3

Solution steps

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

Plug in the value

x = - 2

, assuming the function is continuous at this point

= (- 2)^{2} + 2 t - 1

Simplify

(- 2)^{2} + 2 t - 1 : 2 t + 3

= 2 t + 3

\int (\frac{x + 1}{x})^{2} d x

f (x) = ln ((20 + 2 x)^{4})

y^{^{'}} = 0.05 y - 48000

\int \frac{cos ( \frac{π}{x ^{12}} )}{x ^{13}} d x

4 (x + 2)^{3}
