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

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

1

Solution steps

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

Plug in the value

x = - 2

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

Simplify

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

= 1

f (x) = 2 - x^{2}

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

\frac{d}{d x} (3 x - ln (3 x + 1))

2 x, x

x \to 0 lim (6)
