F.4 數學

y=f(x)=-x^2
(a)
y=-(x-2)^2
y=f(x-2)
圖像會向右平移2格
(b)
y=-(x+3)^2-1
y=f(x+3)-1
圖像會向左平移3格,然後向下平移1格
(c)
y=x^2
y=-f(x)
圖像沿x軸反射

圖像不能畫出黎,但你可以根據呢d描述自己畫出黎!!!

a) the figue translated 2unit to right
b) the figue translated 3unit to left and 1 unit upward
c) the figue reflected by x-axis

I can't find your question.
