What is the domain of f(x) = 5x – 7? a. {x | x > –7} b.{x | x < –7} c. {x | x > 0} d. {x | x is a real number}

d. {x | x is a real number}

Step-by-step explanation:

f(x) = 5x-7 is a linear equation .

There is no restriction on the x values of a linear equation and is always defined for all real values .

Hence we say that the domain of f(x) is all real numbers .

d. {x | x is a real number}
