Question

The domain of the function f open parentheses x close parentheses equals fraction numerator sin to the power of 1 end exponent invisible function application left parenthesis x minus 3 right parenthesis over denominator square root of 9 minus x to the power of 2 end exponent end root end fraction is

  1. [2, 3]    
  2. [2,3)    
  3. [1, 2]    
  4. [1, 2)    

The correct answer is: [2,3)


    The function f left parenthesis x right parenthesis will be defined, if
    negative 1 less or equal than open parentheses x minus 3 close parentheses less or equal than 1 rightwards double arrow blank 2 less or equal than x less or equal than 4
    And 9 minus x to the power of 2 end exponent greater than 0 blank rightwards double arrow blank minus 3 less than x less than 3
    therefore blank 2 less or equal than x less than 3
