Given the function f(x) = 4 - 2x: If the domain is {-4, 0, 5}, find the range.
Solution:
Given,
Function f(x) = 4 - 2x
Domain = {-4, 0, 5}
For an ordered pair (x,y) that a set contain:
X = domain
y = range
In a relation x can have 2 or more than 2 ranges.
f(-4) = 4 - 2(-4) = 12
f(0) = 4 - 2(0) = 4
f(5) = 4 - 2(5) = -6
f(x) = 12, 4, -6.
Therefore, the range is {12, 4, -6}.
Given the function f(x) = 4 - 2x: If the domain is {-4, 0, 5}, find the range.
Summary:
For the given function f(x) = 4-2x and domain {-4, 0, 5}, the range is {12, 4, -6}.
