The point (2,8) is on the graph of f(x)=x3. what is the value of b if the point (0.5,8) is on the graph of f(bx)? if the point (1,3) is on the graph of y=f(x), then what is the corresponding point on the graph of y=−2f(x)?

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
