A 2 column table with 7 rows. The first column, x, has the entries, negative 2, negative 1, 0, 1, 2, 3. The second column, f(x) has the entries, 3, 3, 3, 3, 3, 3. A 2 column table with 7 rows. The first column, x, has the entries, negative 2, negative 1, 0, 1, 2, 3. The second column, g(x) has the entries, 4, 3, 2, 1, 0, negative 1.

Question

The tables given are for the linear functions f(x) and g(x). What is the input value for which f(x) = g(x) is true?

x =

Answer 1

first table, you multiply x by 0 and add 3
second table, add 2 to x

Answer 2

first function:
f(x) = 3
second function:
g(x) = -x + 2

so you want g(x) = f(x)
-x + 2 = 3
-x = 1
x = -1
