二,A football kicked from aheight of 0.5m.The height of the foot ball is modelled by the function b(t) = -5t^2 + 18t+0.5 ,where t is time in second and b(t) is height in metres
1.graph the function for reasonable values of t
2.explain why the values you chose for t in part(a) are reasonable.
3.what is the maximum jeight of the football?
4.At what time does the football reach the maxmum height
5.For how many seconds is the football in the air?
6.Express the domain and range inset notation

一.f(x)=x^2的函数图像会画吧,d(x)就是将f(x)右移3；y轴放大5倍,再向上平移1；具体图像自己画吧；
二.b(t) = -5t^2 + 18t+0.5；作图时保证t>=0；b(t)>=0就可以了；画图时把它转化为d(x)类似的形式；
这种图像的画法是找到中间轴（例如f(x)中为x=0；d(x)中为x=3）；再找到中间轴上的点；接着再随便找两个点（最好关于中间轴对称或者在中间轴的两边）；这样连起来,就是图像了；解题就清楚了.

你会画一y=x^2么，把这个函数画好，再以下几步：
1. 每一个x对应的Y值乘以5
2. y轴向左移动三个单位
3. X轴向下移动一个单位

一个函数方程如下：
d(x)=5(x-3)^2+1
1）从图像f(x)=x^2转换出d(x)的图像
2）找出d(x)的定义域和值域
3）画出d(x)的函数图像
画法是，在f(x)=x^2的基础上，每个x值对应的y值放大5倍，之后图像整体沿着x轴向右移动3个单位长度，沿y轴向上移动1个单位长度。

1）从图像f(x)=x^2转换出d(x)的图像
2）找出d(x)的定义域和值域
3）画出d(x)的函数图像

二， 一个足球从原始高度0.5米被踢出，随后其高度变化被定义为函数b(t) = -5t^2 + 18t+0.5，t代表以秒为单位的时间， b（t）代表以米为单位的高度。
1) 画出这个函数的图像，t需要定义在合理范围内
2）解释为什么你认为在1）的回答中你指出的t的范围是合理的
3）这个足球的最高的高度是多少
4）什么时候这个足球被踢到最高
5）在落地前这个足球在空中飞了多长时间
6）解释定义域和值域插入符号。
