Given the function, f(x) = 8x + 7:
Since it is a linear function, it doesn’t have any constraints or undefined points. Thus, the domain is all real numbers as x-values.
Domain: interval notation: (-∞, ∞)
Set notation: {x | x ∈ R}
The same goes for the range: all real numbers are valid as outputs (y-values).
Range: interval notation: (-∞, ∞)
Set notation: {y | y ∈ R}
