Answer:
78.04 square cm
Step-by-step explanation:
Area of shaded region = area of circle - Area of rectangle
Because the function f(x) =-2+√x+7 has √x, x should be more or equal 0.
Domain is x≥0, or [0,+∞).
The smallest value of x=0, so the smallest value of f(x) is f(0) =-2+√0+7=5,
so range is f(x)≥5, or [5, +∞).
