and this problem were first asked to be right dysfunction in a new notation in the ritual notation. This reads the image of X for the function f is X squared. This is equivalent to saying the function value paired with X is X squared so we can rewrite this and then you notation saying F of X is equal to X squared now, I asked it asked to find the value of F when X is equal to five, this will be equal to five squared, which is equal to 25.
