Define a function \( f : \mathbb{R} \to \mathbb{R} \) by the formula \( f(x) = 9x - 3 \).Prove that \( f \) is one-to-one.Let \( a, b \in \mathbb{R} \), and suppose that \( f(a) = f(b) \). Then \( 9a - 3 = \) [box] , so \( a = \) [box] .\[ \text{eBook} \]

Solution - In the given question, we have to prove that f is one-to-one and also fill the blanks.

Answered: one-to-one. bER, and suppose that f(a)…
