The range of the function f(x) = 3x - 2, is?
- (0, - ∞)
- (-∞, ∞)
- R - (3)
- None of these
Explanation
Given the function f(x) = 3x - 2
This is a linear function with a slope of 3. Since it's linear and defined for all real numbers x, its range is all real numbers.
As x varies from -∞ to ∞, f(x) also varies from -∞ to ∞.
