Answer:
Step-by-step explanation:
To find the inverse of a function in equation form, first I recommend changing the f(x) to a y:
y = -6x + 6
Next step is to switch the x and y:
x = -6y + 6
Now solve for the new y:
x - 6 = -6y and
You can put the inverse notation back in for y like I did in the answer section above.
The circumference is 62.8 cm.
To find the circumference, use 3.14 * 20 = 62.8
