平方如何变成y=4x平方
 

平方如何变成y=4x平方
第一题:描述使等式y=4x²产生的转化过程
answer:expend the openning of its functional image outwards(使它的开口向外扩张)and keep the original axis of symmetry(并保持原有的对称轴)、make sure the image contains point(3,36)(且确保该图像上包括点(3,36))
第二题:描述使等式y=(2x)²
answer:When finished drawing the functional image we discovered that ,(通过画出函数图像知),
the transformation is still to(转化方法仍然是)
expend the openning of its functional image outwards(使它的开口向外扩张)and keep the original axis of symmetry(并保持原有的对称轴)、make sure the image contains point(3,36)(且确保该图像上包括点(3,36))
so the answer is the same as question 1's.(所以本题答案同第一题)
第三题:第二个单词看不清,(可在追问中发来确切拼写),但是大概是让你说明两个等式有相同得数和图像的原因?
answer:
It’s obviously to see that (2x)²=2²·x²=4x²,(显然y=(2x)²=y=4x²是一样的)

...好变态的题
用英文!!!!
