What is the equation of the line graphed below ?

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

to complete this square you have to rotate about the origin 270 degrees clockwise.

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

except if the answer is in the value of money, then, it will matter. it will have to be $0.40, but i can tell this is not a money question, so .4 should be the right one.
