what is the range of this quadratic function? {y|y≥1} {y|y≤1} {y|3≤y≤5} all real numbers
what is the range of this quadratic function? {y|y≥1} {y|y≤1} {y|3≤y≤5} all real numbers
Answer
Explanation:
Step1: Identify vertex of parabola
The parabola opens downwards and the vertex is at the highest - point. From the graph, the vertex has a y - coordinate of 1.
Step2: Determine range
Since the parabola opens downwards, the range is all y - values less than or equal to the y - coordinate of the vertex.
Answer:
${y|y\leq1}$
