Question

Use the image to answer the question.

A parabola is graphed on a coordinate plane with the x-axis ranging from negative 10 to 10 in increments of 1 and the y-axis ranging from negative 10 to 10 in increments of 1.
The vertex of the parabola is marked at left parenthesis 3 comma negative 4 right parenthesis. A dotted line x equals 3 is drawn and labeled “Axis of Symmetry.”


Maribel draws the graph of the function f(x)=2x^(2)−12x+14
. Complete the inequality to show the range of this function using the graph.

(1 point)

The range of the function is y≥ [?]
.

Answer 1

Since the parabola opens upward and its vertex is at (3, −4), the minimum y-value is −4.

The range is y ≥ −4.
