For f(x) = 4x + 1 and g(x) = x2 – 5, find (f - g)(x). o a. x2 - 4x - 6 o b. -x2 + 4x + 6 o c. 4x2 - 19 o d. - x2 + 4x - 4

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
