Answer:
I believe that Kevin is 6 years old now.
Step-by-step explanation:
I used the guess and check method to figure this out.
First, I began by making Daniel 1 years old, two years ago. Kevin was 4 times as old as Daniel two years ago, so he would be 4 at the time. Now, Daniel would be 3 and Kevin would be 6 years old. The statement that Kevin is three years older than Daniel would confirm this, because 6-3=3. Hope this helps, this is my first time answering:)
Step-by-step explanation:
Ooh ape--x I just did this a few weeks ago. To find the inverse, you need to reverse the process. So, instead of adding subtract, and instead of dividing, multiply. It's so easy once you get it.
Start by substituting y for f(x), and then switching x and y, and once you've solved for y I believe, you write f^-1(x) in y's place.
