In a function

f(x)

is defined for

x \in \left[ {0,\;1} \right],

then the function

f\left( {2\;x + 3} \right)

is defined for

View answer and explanation

Correct option: B

x \in \left[ { - 3/2,\; - 1} \right]

The correct answer is B (x ∈ [-3/2, -1]) because it is the interval for x that makes 2x + 3 fall within the defined domain [0, 1] of f(x).
