limit as x approaches-3 of sqrt(5x^2+2x)

x \to - 3 lim (5 x^{2} + 2 x)

39

Decimal

6.24499 \dots

Solution steps

x \to - 3 lim (5 x^{2} + 2 x)

Plug in the value

x = - 3

= 5 (- 3)^{2} + 2 (- 3)

Simplify

5 (- 3)^{2} + 2 (- 3) : 39

= 39

\int \frac{1 + x}{1 - 3 x} d x

x \to 3 lim (\frac{x - 2}{x - 3})

\int \frac{3}{4 ( 4 - 3 x ) ^{7}} d x

4 y^{^{''}} + 9 y = 0

\int \frac{4 x ^{3}}{x ^{4} + 7} d x
