The black graph is the graph of y = f(x). Choose the equation for the red graph. A. y + 4 = f(x) B. y - 4 = f(x) C. y = f(x - 4) D. y = f(x + 4)

The right equation of the red line will be f(x)=y-4 if the equation of the black line is f(x)=y
The equation is like a relationship between variables.
A variable is anything which have a value.
If we see the points of red line and the lack line we can see the value of x in black line is 4 greater than red line so the equation will be
f(x)=y-4 for the red line for the given equation of the lack line which is f(x)=y
