What is the equation shown on this graph?

y=1

Step-by-step explanation:

there is no slope therefore dont place it. however there is a Y intercept.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

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
