Question 1036179
if the equation if f(x) = 3x + 2, then f(5) would be equal to 3*5 + 2 = 17.
the coordinate point would be (5,17).


when you say f(x) = 3x+2, x is the argument and f(x) is the result of applying the argument to the equation.


if you then say find f(5), you are replacing the argument of x with the argument of 5 and applying that to the equation.


f(x) = 3x + 2
your coordinate point is (x, f(x)).
f(5) = 3*5 + 2
your coordinate point is (5,17).


here's a tutorial on functional notation that might help you.
