Answer :
The value of f(x) after evaluating is 11, (-4), 4, 2, and (-7).
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is often represented as y = f(x).
1- Given f(x) = 3x+2, finding x if f(x) = 3
f(3) = 3*3+2 = 11
2- Given f(x) = 3x + 2, finding x if f(x) = -2
f(-2) = 3*(-2)+2 = -4
3- Given f(x) = 16/x, finding x if f(x) = 4
f(4) = 16/4 = 4
4- Given f(x) = x+4, finding x if f(x) = -2
f(-2) = -2+4 = 2
5- Given f(x) = 2x+x-1, finding x if f(x) = -2
f(-2) = 2*(-2)+(-2) - 1 = -7
