Question

The parent is f(x) = log x how do you find the points for g(x) = 1- log x?

Answer 1

Multiply the original output by -1 and add 1.

Explanation:

In looking at the transformation, we first see that the log has been multiplied by -1, meaning that all of the outputs have been multiplied by -1. Then, we see that 1 has been added to the equation, meaning that 1 has also been added to all of the outputs.

To use this to find the points for this function, we must first find points from the parent function. For example, the point (10, 1) appears in the parent function. To find the coordinate pair for the input 10 in the new function, we multiply the output from the parent function by -1 and add 1. `(1*-1)+1=-1+1=0`. This means that the new function will contain the point (10, 0).
