题目翻译：下面哪一个选项是代表图像y=x＋e^x 在x＝0处的切线方程？解答:先求导 y'=1+e^x ， 当x=0时，y'=1+1=2 所以在x＝0这一点处切线的斜率是2 然后根据点（0，1）和斜率2 可以得到这条切线的方程 y=2x+1 答案选择e 对吗？
Any straight line parallel to X-axis in negative direction of Y-axis is given by y= - k, where k is the distance of the line from the X-axis. Here, k=3. Therefore, the equation of the line is y= - 3. To draw the graph of this equation , plot the poi
