Answer:
The x-intercept is the location on the graph when the output is 0.
f(x) > 0 is intervals of the domain where the graph is above the x-axis.
y-intercept is the location on the graph when the input is 0.
f(x) < 0 is intervals of the domain where the graph is below the x-axis.

Answer:
77.2 milliroentgens per hour
Step-by-step explanation:
The first step is to find the constant of proportionality
I ∝ 1/d²
I = k/d²
62.5 = k/(3)²
k = 562.5
The second step is to calculate the intensity at 2.7 meters:
I = 562.5/d²
I = 562.5/(2.7)²
I = 77.2 milliroentgens per hour
