Find the range of the function f(x) = 4x - 1 for the domain (-1,0, 1, 2, 3}.
Accepted Solution
A:
For this case we have a fucnion of the form [tex]y = f (x)[/tex]Where:[tex]f (x) = 4x-1[/tex]By definition, the rank of a function is given by:The set of the real values that the variable y or f (x) takes.So:[tex]f (-1) = 4 (-1) -1 = -4-1 = -5\\f (0) = 4 (0) -1 = 0-1 = -1\\f (1) = 4 (1) -1 = 4-1 = 3\\f (2) = 4 (2) -1 = 8-1 = 7\\f (3) = 4 (3) -1 = 12-1 = 11[/tex]ANswer:The range is: -5, -1,3,7,11
