The graph of y=-2x+2 is positive over the interval (-∞,4) and negative over the interval (4,00). What happens on the graph when x = 4? Explain.
hoose the correct answer below.
C
A. The function is positive at x = 4 because it is negative over the interval (4,00).
B. There is a zero at x = 4 because the function is changing from negative to positive at x = 4.
C.
The function is negative at x = 4 because it is positive over the interval (-∞,4).
D. There is a zero at x = 4 because the function is changing from positive to negative at x = 4.
