What is the maximum value of y = −3(x − 1)² + 4?

Answer and explanation

Correct answer: 4

The expression is in vertex form y=a(x−h)²+k. Since a is negative, the parabola opens downward, so its vertex gives the maximum value. More directly, (x−1)² is always nonnegative. Multiplying it by −3 produces a quantity that is always less than or equal to zero. Consequently, y=−3(x−1)²+4 is always less than or equal to 4. Equality occurs when (x−1)²=0, that is, when x=1. Substitution gives y=−3(0)+4=4. Therefore the maximum value is 4 and option A is correct. The number 1 is the x-coordinate of the vertex, not the maximum y-value; −3 is the coefficient of the squared term, and −4 is not obtained from the expression. The negative leading coefficient confirms that the vertex represents a maximum rather than a minimum.
