What is the domain of the relation graphed below? On a coordinate plane, an ellipse intercepts the x-axis at (negative 4, 0) and (4, 0) and intercepts the y-axis at (0, 1) and (0, negative 1).

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
