Describe the transformation of the graph of f into the graph of g as either a horizontal or vertical stretch.

f as a function of x is equal to the square root of x and g as a function of x is equal to 3 times the square root of x.

i know it's a vertical stretch but i can't explain it.

Abiologist is recording the loss of fish in a pond. he notes the number of fish, f, in the pond on june 1. on july 1 there were 63 fish in the pond, which is 52 fewer fish than were in the pond on june 1. which equation represents this situation? a. f – 52 = 63 b. f – 63 = 52 c. 63 – f = 52 d. f – 63 = –52
