Answer:
f(x) = 2(x+3)+2
Step-by-step explanation:
It really depends on the question and what you want to solve. An exponential function can be written as y = x^2 and if you are solving for y then it will be log(base x) y = 2.
More Examples:
3x = 15
(log both sides with base of 3)
log(3)3x = log(3)15
since log(3)3 = 1 then,
(1)x = log(3)15
x = log 15 / log 3
= 2.465
Irrational kind of means something can't be dealt with, for example, you cannot divide irrational numbers. Rational is something that you can do and will be good to work with, you can divide rational numbers.
