The quadratic function h(t)=-16.1t^2+150 choose the graph representation

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

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
