limit as x approaches-1 of x^2-5x+7

x \to - 1 lim (x^{2} - 5 x + 7)

13

Solution steps

x \to - 1 lim (x^{2} - 5 x + 7)

Plug in the value

x = - 1

= (- 1)^{2} - 5 (- 1) + 7

Simplify

(- 1)^{2} - 5 (- 1) + 7 : 13

= 13

x y^{^{'}} - 2 y = - x^{2} - 2 x - 1

y^{^{'}} = x y^{- 2} - 2 y

x^{2} y^{^{'}} + x y = \frac{y ^{3}}{x}

e^{a r c t a n (4 t^{2})}

\frac{d}{d x} (- \frac{11}{x ^{5}})
