Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q.

-4 + 4x + x2 = 0
a) (x + 2)2 = 4
b) (x + 2)2 = -4
c) (x + 2)2 = 8
d) (x + 2)2 = -8

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
