lim
h-> 0
f(x+h)-f(x)/h
evaluate this limit for the given value of x and function f.
f(x) = x², x= -9

Thelime contains the point(-3,0) and parallel x-3y=3( show all work)

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

Which of the following can be used to explain a statement in a geometric proof?
