Question

Which of the following cannot be rewritten in the form f(x) = ax where "a" is a rational number?

Answer 1

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.
