Which of the following is a transformation of y=f(x) that translates this function down 3,shrinks it horizontally by a factor of 2,and reflects it about the x-axis.
-f(0.5x)-3,求翻译求解释
意思就是把那个函数图象向下移动3个单位,水平缩小一半,然后作这个图象关于x的轴对称函数图象.这样翻译过来以后题目对你没问题了吧?
步骤：
1.y=f(x)
2.y=f(x)-3（向下移动3个单位）
3.y= f(0.5x)-3（水平缩小一半）
4.y= -f(0.5x)-3（作x的轴对称）
