The first three terms of the sequence are A. -1, 0, 3 B. 0, 0, 3 C. -1, 0, 2 D. 0, 2, 6 相关知识点: 试题来源: 解析 A。因为 an = f(n) = n^2 - 2n,所以 a1 = 1^2 - 2×1 = -1,a2 = 2^2 - 2×2 = 0,a3 = 3^2 - 2×3 = 3。
The solution of a differential equation yields a general solution that involves {eq}n {/eq} arbitrary constants where {eq}n {/eq} is the degree of the equation. To select a particular function from the infinite family of functions forming the general so...
Consider the following function f x, y = y^ 2 ln - 2x^5 + 3y^5 Find fy. Compute dy for the given function y = x ln x - x If \ln a = 2, \ln b = 3, and \ln c = 5, evaluate the following: \frac{\ln (a^{-3}b^2)}{\...
To reverse the order we will find the limits of y which will be variable while the limits of x will be constant now the value of x can be found by putting the value of y in the equation. Answer and Exp...
Consider the function, {eq}f(x)=\frac{6x}{x^2-49}. {/eq} a) Use interval notation to indicate where f(x) is decreasing. b) Use interval notation to indicate where f(x) is concave up. c) Use interval notation to indicate where f(x) is conc...

We obtain the quadratic equation of best fit by using quadratic regression (STAT/CALC/5:QuadReg/VARS/Y-VARS/1:Function/1;Y1/ENTER). Note that r2 = .997 here, so we expect a very good fit: y = .402x2− 1600.282x + 1593498.2. This appears to be a good fit and we expect a ...
