Answer
True.
Work Step by Step
The equation y=f(x), read as "y equals f of x," tells us that x is a function of y. In this case, we can input a value of x into the function to find its corresponding y-value, with the resulting ordered pair (x,f(x)).
We are given that x=7 and f(7)= 50, so the resulting ordered pair is (7,50). This statement is true.
