Plz help! Are these statements always, sometimes, or never true 12. The graph of f(x) =ax^2 is narrower than the graph of g(x) = dx^2 when d = -a.

13. The graph of f(x) = ax^2 opens in the same direction as the graph of g(x) = dx^2
when d = 101

14. The graph of f(x) = (ax)^2 opens in the same direction as the graph of
g(x)=dx^2 when a^2= d.

15. The graph of f(x) = (ax)^2 is narrower than the graph of g(x) = dx^2 when
0 < a^2 < d.

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
