1: write a function that represents this process:
take a number, x.
multiply it by 4.
subtract 2 from the result.
then find the inverse of this function. does the inverse represent the reverse of the process above? explain why or why not.
2: show why, for linear functions, a vertical translation is equivalent to a horizontal translation. for a linear function, what horizontal translation is equivalent to a vertical translation of 3 units up?
3: alex says that the function f(x) = (3x)^2 represents a vertical stretch of the quadratic parent function by a factor of 3. marta says that it represents a horizontal compression by a factor of 1/3. decide whether one student is correct, both are correct, or neither is correct.
4: for an unknown parent function f(x), write a function g(x) that is:
vertically stretched by a factor of 2,
shifted up 5 units, and
shifted right 4 units.
explain how your function accomplishes these transformations.

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below. the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
