Answer:
Step-by-step explanation:
To find the rate of change of a function, we are looking for it's slope.
We can find the slope of a line by seeing it's rise over run.
Basically - how much the line's y increases divided by how much the line's x increases.
We can see that the y drops from 1 to -1 in 1 x value. This means the change in y is , however in this case it is -2 as we are dropping.
The change in x is 1 .
This means that the slope (rate of change) is .
Hope this helped!
I'm assuming that you mean
because if you meant
then u would simplify and you couldn't make it the subject.
Under this assumption, we start with
We multiply both sides by
We expand the left hand side:
We move all terms involving u to the left and all terms not involving u to the right:
We factor u on the left hand side:
We divide both sides by
