Two numbers r and s sum up to -2 exactly when the average of the two numbers is \frac{1}{2}*-2 = -1. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C.

See the answer. Find the limit. lim (e−2x cos x) x→∞ lim x 2+ (x^2+2x-8)/(x^2-4) Two numbers r and s sum up to -2 exactly when the average of the two numbers is \frac{1}{2}*-2 = -1. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. Marcos Pereira. Answered October 25, 2017.

Answered October 25, 2017. Originally Answered: What is limit x->-infinity of x*e^- (2x)? To evaluate lim x → − ∞ x e 2 x. This is an indetermination of the type ∞ ∞ using the L’Hopital rule. lim x → − ∞ ( x) ′ ( e 2 x) ′ = lim x → − ∞ − 1 2 e 2 x = − 1 2 e 2 ⋅ ( − ∞) = − 1 2 e ∞ = − ∞.

In this Chapter, we will generalize the concept and Cos 2X formula of one such trigonometric ratios namely cos 2X with other trigonometric ratios. Let us start with our learning! Example $\displaystyle \lim_{x\to 0}\, \frac{\sin x}{x}=\lim_{x\to 0}\, \frac{\frac{d}{dx}(\sin x)}{\frac{d}{dx}(x)}=\lim_{x\to 0}\, \frac{\cos x}{1}=1.$ Get an answer for 'lim(x->0)((1-e^2x)/(1-e^x))' and find homework help for other Math questions at eNotes We’ve discounted annual subscriptions by 50% for COVID-19 relief—Join Now! icon-close The value of the $$\lim\limits_{x\to-\infty}{(4x^2-x)^{1/2} +2x}$$ is?
