a. Factor the following polynomial completely. (2 poi Apalptent for partial factoring, 1 for final) (y + 4)2 – 2(y + 4) +1 b. Is this the product of a perfect square trinomial? Teresa says it is, Rico says it's not. Who is correct? (1 point) 1 polnt Droblem-5

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
