please someone help me with this question i really need help asap

Question

Question 1:The number of cars sold per month can be modeled by f(x) = 0.03x³ + 0.4x² + 0.7x + 75, where x represents the number of months since April. Let g(x) = f(x) − 25. Which of the following gives the rule for g and the correct explanation of the meaning of the transformation in terms of monthly car sales?

A.) 0.03x3 + 0.4x2 + 0.7x + 50

vertical shift 25 units down

decrease of 25 units per month

B.) −0.03x3 + 0.4x2 − 0.7x + 100

vertical shift 25 units up

increase of 25 units per month

C.) 0.03x³ + 0.4x² + 0.7x + 100

vertical shift 25 units up

increase of 25 units per month

D.) 0.03x3 + 0.4x2 + 0.7x + 25

vertical shift 50 units down

decrease of 50 units per month

Question 2: The table shows the numbers of cars manufactured by a company for selected years. Identify a polynomial function for cars manufactured in thousands where x represents the years since 1990.

A.) P(x) = 0.2x³ + 0.5x² + 0.4x + 0.3

B.) P(x) = 0.5x³ + 0.5x² + 0.4x + 0.4

C.) P(x) = 0.2x³ + 0.2x² + 0.3x + 0.3

D.) P(x) = 0.5x³ + 0.2x² + 0.3x + 0.4

Answer 1

1) A: vertical shift down of 25 units

2) both A and D work for 1991, A works for 1993, D doesn't when you plug in x=3

Answer is A
