Answer:
25%
Step-by-step explanation:
The formula to find percent increase is . We're given the initial value as 120 and the final value as 150.
Therefore, the percent increase is 25%.
That would be f(x) = 4|x|. Reason is, the bigger the number that's multiplied by |x|, the narrower the graph will be. The opposite is true for the smaller the number, & so f(x) = .5|x| will be wider.
Hope this helps!
