对于任意函数f(x),如果要把这个函数向左平移a个单位(a>0),那么得到的函数就是f(x+a);如果要把这个函数向右平移a个单位(a>0),那么得到的函数就是f(x−a); 比如f(x)=x2,下图就是向左或向右平移1个单位得到的函数图像,f(x)=(x+1)2,f(x)=(x−1)2 对于任意函数f(x),如果要把这个函数向上...
A General Note: Vertical Shift Given a function f(x)f(x), a new function g(x)=f(x)+kg(x)=f(x)+k, where kk is a constant, is a vertical shift of the function f(x)f(x). All the output values change by kk units. If kk is positive, the graph will shift up. If kk is...
A function can be shifted vertically by adding a constant to the output. A function can be shifted horizontally by adding a constant to the input. Relating the shift to the context of a problem makes it possible to compare and interpret vertical and horizontal shifts. Vertical and horizontal ...
