  • 1.a) x--> -x

    b).-x ---> -x+2 (2-x)

    c).flip the whole graph and double the y-coordinate on every point of graph

    这才是图像的transformation

    2.先画出y=ln x的图像,然后按1.的步骤做

    3.1)(中文表示不清楚):take e as base and take right hand side and left hand side as your exponent.得到 e^ (-2ln (x-2) = e^10

    2).由代数性质(x ^ nm = x^m * x^n),我们得到e^(-2) * e^(ln (x-2)) = e^10

    3).由对数性质(e^ ln(x) = x)得到 e^(-2) * (x-2) = e^10

    4).剩下的就简单了,两边同除e^(-2),+2,最后结果是 x = 2 - e^12
