limit as x approaches-3 of sqrt(4x+28-4)

x \to - 3 lim (4 x + 28 - 4)

23

Decimal Notation

3.46410 \dots

Solution steps

x \to - 3 lim (4 x + 28 - 4)

Plug in the value

x = - 3

= 4 (- 3) + 28 - 4

Simplify

4 (- 3) + 28 - 4 : 23

= 23

\frac{d}{d x} (\frac{7 x}{2 x ^{3}})

\frac{d}{d x} ((x^{3} + 2)^{2} (x^{5} + 4)^{4})

\int (2 x + 5)^{2} d x

\frac{d}{d x} (\frac{e ^{x}}{4 x ^{6}})
