Question

Domain and range of f(x) = 4-4x

Answer 1

It's a linear function in slope-intercept form (y = mx + b)

f(x) = 4 - 4x = -4x + 4

m = -4, b = 4.

Domain of a linear function is the set of all real numbers.

Range of a linear function where m ≠ 0 is the set of all real numbers.

Answer:
`Domain=\mathbb{R},\ Range=\mathbb{R}`
