The correct Answer is:
To solve the given problem, we need to analyze both statements and determine their validity step by step. ### Step 1: Analyze Statement 1 We start with the function: \[ f(x) = \frac{ax + b}{cx + d} \] We need to determine if this function can attain the value \( \frac{a}{c} \) given that \( ad - bc \neq 0 \). #### Step 1.1: Set the function equal to \( \frac{a}{c} \) We set: \[ f(x) = \frac{a}{c} \] This gives us the equation: \[ \frac{ax + b}{cx + d} = \frac{a}{c} \] #### Step 1.2: Cross-multiply to eliminate the fraction Cross-multiplying gives: \[ c(ax + b) = a(cx + d) \] #### Step 1.3: Expand both sides Expanding both sides results in: \[ acx + bc = acx + ad \] #### Step 1.4: Simplify the equation Subtract \( acx \) from both sides: \[ bc = ad \] #### Step 1.5: Analyze the condition Since we know \( ad - bc \neq 0 \), this means \( bc \neq ad \). Thus, the equation \( bc = ad \) cannot hold true, indicating that \( f(x) \) cannot equal \( \frac{a}{c} \). ### Conclusion for Statement 1 Therefore, Statement 1 is **correct**: \( f(x) \) cannot attain the value \( \frac{a}{c} \). --- ### Step 2: Analyze Statement 2 Now we need to analyze the function: \[ g(x) = \frac{b - dx}{cx - a} \] We need to find the domain of this function. #### Step 2.1: Identify when the denominator is zero The function \( g(x) \) is undefined when the denominator is zero: \[ cx - a = 0 \] #### Step 2.2: Solve for x Solving for \( x \) gives: \[ cx = a \] \[ x = \frac{a}{c} \] #### Step 2.3: Determine the domain The domain of \( g(x) \) includes all real numbers except where the denominator is zero: \[ \text{Domain of } g(x) = \mathbb{R} - \left\{ \frac{a}{c} \right\} \] ### Conclusion for Statement 2 Therefore, Statement 2 is also **correct**: The domain of \( g(x) \) is \( \mathbb{R} - \left\{ \frac{a}{c} \right\} \). --- ### Final Conclusion Both statements are correct: - Statement 1: \( f(x) \) cannot attain the value \( \frac{a}{c} \). - Statement 2: The domain of \( g(x) \) is \( \mathbb{R} - \left\{ \frac{a}{c} \right\} \). ---

To solve the given problem, we need to analyze both statements and determine their validity step by step. ### Step 1: Analyze Statement 1 We start with the function: \[ f(x) = \frac{ax + b}{cx + d} \] We need to determine if this function can attain the value \( \frac{a}{c} \) given that \( ad - bc \neq 0 \). ...
