Which function is best represented by this graph?

• g(x) = 6x + 4

What is the rate of change of y with respect to x?

• 10

• 17

• -10

• -17

• The zeros are -8 and 2, because the factors of g are (x+ 8) and (x − 2).

• The zeros are -8 and −2, because the factors of g are (x+ 8) and (x+ 2).

• The zeros are -2 and 8, because the factors of g are (x+ 2) and (x − 8).

• The zeros are 2 and 8, because the factors of g are (x − 2) and (x − 8).
