The numerator can be … NettetWhat this question means is what number is 7x-2 approach if x become extremely small. 1. If x is -1, 7x-2 is -9. 2. If x is -10, 7x-2 is -72. 3. If x is -100, 7x-2 = -702. Here's a pattern, as x become smaller and smaller, 7x-2 become smaller and smaller as well. That means when x approach negative infinity, 7x-2 approach negative infinity as well.

Let a be a real number. Then, lim x → ap(x) = p(a) lim x → ap(x) q(x) = p(a) q(a) when q(a) ≠ 0. To see that this theorem holds, consider the polynomial p(x) = cnxn + cn − 1xn − 1 + ⋯ + c1x + c0.

Nettet16. mar. 2015 · Okay, so for both of these functions at $ (0,0)$ the denominator is zero along $3x^4+2y^2$ and $x^2+y^6$, respectively, so I cannot simply evaluate the limit of a sequence approaching points along this line to determine the limit. Everywhere else however, including $ (1,0)$ the limit exists and is hence continuous.
