PLEASE HELP the line models the height of a glider y in feet over x hours

find the y intercept of the graph

this is a good question! i'll do some research and come back when i have the answer!

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
