5k^2 = 25 ^ 3 = 15625
5k^6 = 15625
Hope this helps
Subtract 1:
x/4=2
multiply by 4:
x=8 which is the answer
As per definition
In. a function every domain has an unique range of it
Here
- f(4)=6
- f(10)=-2
- f(13)=7
- d(15)=8
- f(10)=11
f(10) has two corresponding values hence it's not a function
10 meaning the biggest number and then subtract by 4 since it’s the lowest number and you get 6.
It would be 2.1×10 to the power of 13
