The given function is,
f(x)= x - 3.141
Replacing f(x) by y,in the above equation
y = x - 3.141
Comparing, with slope intercept form of line,→ y = m x + c
→As, it is a linear function in two variables,having slope 1, and,
Y intercept = -3.141
The exponential function can be described by the rule:
f(x)=
, where m is a real number , Domain of m is all real number , m∈ [-∞,∞].
and x is a variable, whose domain is, -∞≤x≤∞.
The exponential function is not defined when, m=0 as well as , x=0.
