Question

If f left parenthesis x right parenthesis equals 4.5 to the power of x, then what is the value of f left parenthesis x right parenthesis if x equals 3?

  1. 25
  2. 125
  3. 250
  4. 500

hintHint:

Put x = 3 in the given function

The correct answer is: 500


    For x=3
    f left parenthesis x right parenthesis equals 4.5 cubed
    equals 4 cross times 125
    equals 500
