Explanation

Exponential functions have the form:

[tex]f(x)=a\cdot x^b.[/tex]

The initial value of the function f(x) is given by the value of f(x) when x = 0:

[tex]\text{ initial value }=f(0)=a\cdot x^0=a\cdot1=a.[/tex]Answer

For an exponential function:

[tex]f(x)=a\cdot x^b,[/tex]

we have:

[tex]\text{ initial value }=f(0)=a[/tex]
