Number 16 only i’ve tried everything but i can’t figure it out

What are the domain and range of the function f(x)=2^x+1

Someone answer asap for ! 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

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.
