Question

The values on both axes range from negative 5 to 5 in
increments of 1. The curve begins at left parenthesis negative 2
comma 0 right parenthesis and slopes upward from left to right,
passing through left parenthesis negative 1 comma 2 right
parenthesis, left parenthesis 2 comma 4 right parenthesis, and
left parenthesis 4.2 comma 5 right parenthesis. All values are
approximate.
What is the vertex of the quadratic function that is related to the
square root function in the graph?
(1 point)
(0, −2)
(0, 2)
(−2, 0)
(2, 0)

Answer 1

(-2, 0)

The square-root graph starts at (-2, 0); squaring that function produces the related parabola whose vertex is at the starting point (-2, 0).
