Question

The value of b in an exponential function f(x) = a.bx is __________.

  1. straight b not equal to 1
  2. straight b equals 0
  3. straight b equals negative 1
  4. straight b not equal to 0

The correct answer is: straight b not equal to 1


    f(x) = a.bx for exponential function (b>0 and b≠ 1)
    b cannot be 1,-1

    for any exponential function f(x)=ax  a should be (a>0 and a≠ 1)
    a cannot be negative neither a can be equals to 1

    If f(x) = 4.5x, then what is the value of f(x) if x = 3.

    To find the value of f(x) at any value of x ,just replace x with the given value
    for eg : if f(x)=ax and we have to find value of f(x) at x=3
    f(x) at 3 will be f(3)=a3
