Exponential function:
Exponential function is function in which any exponent as variable raised over a constant
For exp:
[tex]f(x)=(0.2)^x[/tex]
[tex]f(x)=(7)^x[/tex]
[tex]f(x)=(e)^x[/tex]
here , 0.2 , 7 and e are constants
Power function:
Power function is function in which any exponent as constant raised over a variable
For exp:
[tex]f(x)=x^2[/tex]
[tex]f(x)=x^{1.2}[/tex]
[tex]f(x)=x^{-7}[/tex]
