linear functiontextbooksThis paper compares sections on functions and linear functions from two Korean textbooks and an American standards-based textbook (University of Chicago School Mathematics Project [UCSMP] Algebra) to understand differences and similarities among these textbooks through horizontal and ...
Inverses of Linear Functions Example Given y, solve for x: Example (continued) The equation defines x as a linear function of y. This function is called the inverse of the original function. We write Equivalence The two equations and are equivalent. One is satisfied by a pair (x,y) ...
Interpret and compare properties oflinear functionsfrom tables, graphs, or equations.───从表,图,和方程来解释和比较线性函数的特点。 Results The Class of piecewiselinear functionsis more general that that of step functions.───结果分段线性函数是比阶梯函数更广的函数类。
Linear Functions(线性函数) f(x)=mx+b DEFINION Two varisbles y and x are proportional(正比)(to one another) if one is always a constant multiple of the other; that is, if y=kx for some nonzero constant k . If the variable y is proportional to the reciprocal 1/x, then sometimes...

Calculate, or predict, a future value by using existing values. The future value is a y-value for a given x-value. The existing values are known x-values and y-values, and the future value is predicted by using linear regression. You can use these functions to predict future sales, inv...
Linear FunctionsA Function is special relationship where each input has an output.A function is often written as f(x) where x is the input:05100246810 f(x) = xResults from f(x) = xxyy = x 1 1 y = x = 1 2 2 y = x = 2 3 3 y = x = 3 4 4 y = x = 4 5 5 y =...

Linear functions & Quadratic functionsLinear Function The equation of alinear functionis L(x)=mx+b, and its graph is a line. If (x1,y1) and (x2,y2) are two any points on the line, the slope of the line is m=___, and the y-intercept of the graph is b, the value of y wh...
linear functions词汇线性函数的词汇包括斜率、截距、图形表示、函数形式等。具体如下: 1. 斜率(Slope):线性函数中,斜率表示函数的变化率,即直线的倾斜程度。在数学表达式中,斜率通常用字母m表示。 2. 截距(Intercept):截距分为两种,一种是y截距,另一种是x截距。y截距是指直线与y轴的交点的纵坐标,在数学表达式...
