The range of the real valued function f(x)= 9-x^2 is

Options

  1. A[-3,3]
  2. B[-3,0]
  3. C[0,3]
  4. D[-2,2]

Correct answer

C. [0,3]

Step-by-step solution

aligned & f ( x )= 9- x ^2 & Here -3 x 3 & 0 x ^2 9 & -9 - x ^2 < 0 0 9- x ^2 3 & 0 f ( x ) 3 aligned So, the range of the given function is [0,3]
