please answer all parts of the question and explain TIA

Use the following information to answer the next question. The. graph of y = f(x) is shown below. (5,10) -8-7-6-5-4-3-2-1 5678910 odnL 18. a) When the graph of y = f (at) is sketched, name an exact point in quadrant 1, that is not an invariant point. [1 Mark] b) Determine the invariant point of y = 1/f(:13) in quadrant 2, accurate to two decirnals. [1 Mark] c) Is x = 1 part of the domain of y = 1/f(.cc)? Explain. [1 Mark] d) If the point (3, 6.48) is on the graph of y = ' /f (:0) then what is the point on the graph of v : flx) (give the coordinates to the nearest integers) [1 Mark]
