The tables represent the functions f(x) and g(x).
A table showing g(x) equals 2 x plus 15 with 2 columns and 7 rows. The first column, x, has the entries, negative 15, negative 12, negative 9, negative 6, negative 3, 0. The second column, g(x), has the entries, negative 15, blank, blank, blank, blank, 15.
Which input value produces the same output value for the two functions?
Hint, because the tables are incomplete, you will need to solve by setting the equations equal to each other.
A. x = -12
B. x = -9
C. x = -6
D. x = -3
