Answer:No it's not an exponential equation in which f(x)is not qualified to an exponential number. no number from 1 - 20 can be used and get subtracted by 2 to give a square number.
eg-
4×2-2≠ square number
Step-by-step explanation:
Answer:
20:60 12:36 2:6
The second number is going to be 3 times as big as the first ine
The value of f(6) = 7
2 x 6 = 12 - 5 = 7
Combine Like terms and do the Equation normally
8+n^2
