Question

What is the range of -x2+x+4.75?

GPT 3.5
The range of the function -x^2 + x + 4.75 is all real numbers less than or equal to 4.75. This is because the coefficient of the highest degree term (-1 in this case) is negative, which means that the parabola opens downward. Since the vertex of the parabola is at (0.5, 4.75), the maximum value of the function is 4.75, and all other values are less than or equal to this.
