The correct answer is:
F(x) is read as “F of x” ; F is the graph at a particular value of x; and y is equal to F(x).
Step-by-step explanation:
f(x) is read as "f of x" by definition.
F is the function, and f(x) is the function at a given value of x; for instance, f(3) would be where the function is at the value x=3.
f(x) is another way of writing an equation, except it is in function form. This means it is the same as y=.
