How to draw an image with y = 3 * (x-1)? How to draw an image of y = log3 (x-1)?

How to draw an image with y = 3 * (x-1)? How to draw an image of y = log3 (x-1)?

First draw the image y = log3 (x)
No problem
Move the image one unit to the right
Y = log3 (x-1)

Y = - 3 | x | 1 how to draw an image?

A: y = - 3|x| + 1
When X & lt; = 0, y = 3x + 1
When X & gt; = 0, y = - 3x + 1
The image is as follows:

How to draw the image of y = 2 ^ - x, y = X-1 / 1

y=2^-x=(1/2)^x,
The image with exponential function y = (1 / 2) ^ x is y = 2 ^ - X image,
Y = X-1 / 1 is the error of y = (x-1) / X,
y=(x-1)/x=1-1/x,
Make the image of inverse scale function y = - 1 / x, and then move up one unit,
The image y = (x-1) / X is obtained

How to draw an image with x ^ 2 + y ^ 2 less than or equal to 1?

If the center of the circle is at the origin and the radius is 1, the image is the boundary of the circle and all the inner parts of the circle
