Question

The value of a if f(x) = a.3x is __________.

  1. 12
  2. 5
  3. 6
  4. 2

The correct answer is: 6


    We know, f(x) = a.3x
    When x = 0, f(0) = a.30 =a.1=a ,but we are given f(x) =6 at x=0
    a=6

    to find the value of function at certain point just replace the variables with the given points

    The range of the exponential function f(x) = 5.2x is _________.

    for any  function f(x) =ax (if a>1) the range of f(x) is (0,infinity)
    therefore for f(x)=k.ax the range would be (0*k,infinity*k) that is (0,infinity)
