Is the given function continuous for x greater than -2? f(x) = x²-1/x-1
Select one:
a. No, since the function can be graphed using analytical
methods.
b. Yes, since the function will always be defined for x greater than -2.
c. No, since the function is undefined for some values of x that are greater than -2.
d. Yes, since the function can be graphed using a table of values only.

Is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis.

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

If f(x) = 3x-2 and g(x) =2x+1 find (f-g)(x)
