Answer:
The function decreases across all real numbers x where x < 1.5.
Step-by-step explanation:
We have



This represents an upward-opening vertical parabola
The vertex denotes a minimum point
The vertex is located at (1.5,-6.25)
We know that
The function is decreasing within the interval ----> (-∞, 1.5) x < 1.5
This means----> the function is continuously decreasing for all real x values under 1.5
Conversely, the function is increasing within the interval ----> (1.5, ∞) x> 1.5
Thus, for all real x values greater than 1.5, the function is increasing
Check the attached figure for further clarification
Therefore
The true statement is
The function decreases across all real numbers x where x < 1.5.
