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

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

6

Solution steps

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

Plug in the value

x = 1

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

Simplify

= 6

cos (\frac{x}{x + 2})

\int \frac{1}{x 1 + x ^{4}} d x

f (x) = \frac{1}{( 2 x + 1 ) ^{2}}

\frac{d y}{d x} = \frac{7 x + 2 y}{7 x + 2 y + 2}

f (x) = 2 - 7 x, (- 2, 4)
