Regarding the graph function f(x), it is only F(5) = -1 that is true. Option B is the correct answer.
The slope (m) of the graph is
m = (4 - 0) / (0 - 4)
m = -1
From general linear equation: y = mx + c
The equation of the function is;
y = -x + 4
f(x) = -x + 4
Let us check all the options one by one.
If x = 0,
F(0) = 4 This is not true
If x = 5
F(5) = -5 + 4
F(5) = -1 This is true.
Therefore, regarding the graph function f(x), it is only F(5) = -1 that is true. Option B is the correct answer.
