determine which of the following statements is true concerning the values described in column #1 and column #2.

column #1: the x-coordinate of the vertex of the graph of
y = −2x2 − 4x + 12
column #2: the x-coordinate of the vertex of the graph of
y = x2 − 4x + 3
a. the value found in column #1 is greater than the value found in column #2.
b. the value found in column #1 is less than the value found in column #2.
c. the value found in column #1 is equivalent to the value found in column #2.
d. the relationship between column #1 and column #2 cannot be determined by the information given.
