Step-by-step explanation:
Change it into this
(2x-3)(2x-3)
Then multiply the insides and outsides and add them
(2x*2x) + (2x* -3) + (-3*2x) + (-3*-3)
Simplify
4x^2 - 6x -6x + 9
Simplify again
4x^2 - 12x + 9
I guess the function is a parabola with vertex at (0,0) and opens down so the range is (-infinity, 0].
Answer:
2 jars
