Step-by-step explanation:
It has to be less than or equal to $58.50
You slowly go down the bottom row and multiply each digit by the top row.
Answer:
y = 1/2x
Step-by-step explanation:
The x seems to double the size of the y on the points.
Answer:
The inverse i.e f^-1 (x) is (x-1)/2
Step-by-step explanation:
The main method for finding inverse function is as follows:
We let y =f(x), and write the function as y = 2x + 1.
Next, we swap the x and y, then rearrange to make y the subject. So i.e:
x = 2y + 1 (just swapping x and y)
x - 1 = 2y
y = (x-1)/2 (solving for x).
So f^-1 (x) = (x-1)/2
