Question 5: 20 ptsThe number of toys sold per month can be modeled by f(x) = 2x4 + x3 + 6x + 5, where x represents the number ofmonths since June. Let g(x) = f(x) + 7. Which of the following gives the rule for g and the correct explanation of themeaning of the transformation in terms of monthly toy sales?

Answer 1

The function f(x) represents the number of toys sold per month, where "x" represents the number of months since June

$f(x)=2x^4+x^3+6x+5$

This function was transformed resulting in the function:

$g(x)=f(x)+7$

When you add a constant to a function, the resulting transformation is a vertical translation up. In this case, the function f(x) was translated 7 units up.

In terms of the variables, this translation in
