Question

The value of a if f left parenthesis x right parenthesis equals a.3 to the power of x is ______.
x f(x)
0 6
1 18
2 54
3 162

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

hintHint:

Any number with power 0 =1

The correct answer is: 6


    We know, f left parenthesis x right parenthesis equals a times b to the power of x
    When x = 0, f left parenthesis x right parenthesis equals a.3 to the power of 0
    space equals a
    a equals 6
