limit as x approaches 2 of 3x^2+2x-1

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

15

Solution steps

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

Plug in the value

x = 2

= 3 \cdot 2^{2} + 2 \cdot 2 - 1

Simplify

3 \cdot 2^{2} + 2 \cdot 2 - 1 : 15

= 15

\int \frac{1}{x ^{2} + a} d x

\int \frac{y ^{4} + y ^{2} - 1}{y ^{3} + y} d y

n = 0 \sum \infty \frac{5}{2 ^{n}}

\frac{5}{( s - 2 ) ( s - 3 ) ( s - 6 )}

\int cot (\frac{θ}{5}) d θ
