Question 17 • Precalculus
At x = 7, the numerator approaches −2(7²) + 14 = −84, a negative number. Just to the right of 7, the denominator (x − 7)(x + 7) is positive but very close to zero, so the function approaches negative infinity. Therefore, the statement “As x approaches 7 from the right, y approaches negative infinity” is correct.
