Which one of these is not like the others? [Things to think about, but not limited to…… what way does the graph open? Signs of the quadratic term, linear term, constant term? Domain? Range? You might also put them into desmos. com and look at the graphs!]

Function 1: y = 6x^2 - 4x - 8
Function 2: y = 3x^2 - 3x + 1
Function 3: y = -2x^2 + x + 5
Function 4: y = 0.5x^2 - 5x + 3

Use at least two sentences to explain which one is not like the others and what in the function gives you that information. Use correct mathematical terminology. You might use some of the words: constant, quadratic term, linear term, opens up, opens down, positive, negative, domain, range, left, right.
