The expression [ x² - 4 ] doesn't depend on 'a', 'b', or 'y'.
It only depends on 'x'.
You have said that 3x = 5, so x = 5/3.
Therefore, I may now write '5/3' in place of 'x' in the expression:
x² - 4 =
(5/3)² - 4 =
(25/9) - 4 =
(25/9) - (36/9) =
(25 - 36) / 9 = -11/9 = - (1 and 2/9)
Answer:
This is a problem with translations in the x-axis.
if we have a real positive number a, then for a function f(x), the graph of the function f(x - a) will be the graph of f(x) but translated by a units to the right.
then, if we have f(x - 2) we translate the graph 2 units to the right, if we have f(x + 4) we translate the graph by 4 units to the left.
Then the order, from left to right, is:
f(x + 3)
f(x +2)
f(x)
f(x - 1/2)
f(x - 4)
f(x - 7)
