Given that (-3, 5) is on the graph of f(x), find the corresponding point for the function f(x) − 4.

OpenStudy (phi):

when they give you a "point on the graph" they are giving you the combination ( x , f(x) )

OpenStudy (phi):

so when they give you (-3, 5) what is f(x) when x is -3 ?

OpenStudy (the_fizicx99):

f(x) is another way of saying y, so what is f(x) @Autumnlee95

OpenStudy (ranga):

f(x) - 4 is f(x) shifted down by 4 units. Down means down the y-axis. So the y-coordinate of all points on the graph will also be shifted down by 4 units.
