What happens on the graph when x = 4 is; The graph function is equal to zero
How to Interpret Linear Graphs?
The information that we have is:
"The graph of y = -1/2x + 2 is positive over the interval negative infinity and 4 and negative over the interval 4 and infinity."
Now, the question wants us to know what happens on the graph when x = 4.
Well, if for values of x smaller than 4 the graph is negative and for values of x larger than 4 the graph is positive, this must that the graph must cross the x-axis at some point, then with only that information, we can conclude that the graph is equal to zero when x = 4.
Plugging in 4 into the equation gives;
y = -(1/2)*4 + 2
y = 0
