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)
再问: 谢谢大神了,第三题全是乱码,看不见抱歉。第三题是slow algebraically that the two transformation produce the same equation and graph
再答: slow(应该是Show吧) algebraically that the two transformation produce the same equation and graph:从代数角度说明,这两种转化产生相同等式和图像的原因。 answer已给出
再问: 谢谢大神了
