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, +∞).
B
b=
Where k is a constant of proportionality.
b=18, c=4,d=9, e=6
Finding the value f k,
18=
6k=18
k=3
The equation then is;
b=
The constant of variation=3
