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.

Jonathan pays $1.90 per pound for potatoes. he buys 8.3 pounds of potatoes. he determines that he will pay $15.77, before tax, for the potatoes. which best describes the reasonableness of jonathan’s solution? jonathan’s answer is reasonable because there are two decimal places in the factors and two in the product. jonathan’s answer is unreasonable because there are three decimal places in the factors and two in the product. jonathan’s answer is reasonable because is 16, and 16 is close to 15.77. jonathan’s answer is unreasonable because is 8, and 8 is not very close to 15.77.
