Question 948563: How do you put (2,4) and (4,-2) in function notation form?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! f(2) = 4
f(4) = -2
for example:
suppose you have a function that takes the value of x and squares it.
the function would be f(x) = x^2
now if you evaluate that function for the value of x = 2, you will get:
f(2) = 2^2 which becomes f(2) = 4
now if you have a function that takes the the square value of x and then multiplies it by -1, then that function would be:
f(x) = -sqrt(x)
now if you evaluate that function for when x = 4, you would get:
f(4) = -sqrt(4) which becomes f(4) = -2
