The correct Answer is:
To solve the problem, we will analyze both statements step by step. ### Step 1: Analyze Statement I The equation given is \( |(x - 2) + a| = 4 \). 1. **Break down the absolute value**: The absolute value equation can be split into two cases: \[ (x - 2) + a = 4 \quad \text{or} \quad (x - 2) + a = -4 \] 2. **Rearranging the equations**: - From the first case: \[ x - 2 + a = 4 \implies x = 6 - a \] - From the second case: \[ x - 2 + a = -4 \implies x = -2 - a \] 3. **Finding the number of solutions**: The solutions for \( x \) are: \[ x = 6 - a \quad \text{and} \quad x = -2 - a \] For these to be distinct solutions, we need to ensure that these two values are different: \[ 6 - a \neq -2 - a \] This simplifies to: \[ 6 \neq -2 \quad \text{(which is always true)} \] Therefore, there are always two distinct solutions for any value of \( a \). 4. **Checking the interval for \( a \)**: The statement claims that there can be four distinct real solutions if \( a \) belongs to the interval \( (-\infty, 4) \). However, as we have shown, there can only be two solutions regardless of the value of \( a \). Thus, **Statement I is incorrect**. ### Step 2: Analyze Statement II Statement II claims that the number of points of intersection of the curve represents the solution of the equation. 1. **Understanding the intersection**: The solutions to the equation \( |(x - 2) + a| = 4 \) can be interpreted graphically as the points where the line \( y = (x - 2) + a \) intersects the horizontal lines \( y = 4 \) and \( y = -4 \). 2. **Conclusion about intersections**: Since the number of intersection points corresponds to the number of solutions to the equation, **Statement II is correct**. ### Final Conclusion - **Statement I** is incorrect because the equation cannot have four distinct solutions for any value of \( a \) in the given interval. - **Statement II** is correct as it accurately describes the relationship between the number of intersection points and the solutions of the equation. ### Answer The correct option is (d): Statement II is correct but Statement I is incorrect.
