Question

Range of the function f(x)= Ix–3I is a)[-3,3] b)ℝ c)(3,∞) d)(-3,∞)

Answer 1

as, it is inside modulus , so , f(x) would always be positive or zero

$|x - 3| \geqslant 0$

remove modulus from -3

$- 3 \leqslant x \leqslant 3$

so,

ans is option A [-3,3]

Answer 2

Answer:

as, it is inside modulus , so , f(x) would always be positive or zero

|x - 3| \geqslant 0∣x−3∣⩾0

remove modulus from -3

- 3 \leqslant x \leqslant 3−3⩽x⩽3

so,

ans is option A [-3,3]

hope it helps
