What is the y intercept of f(x)=(1/2)^x?

Read the situations in the table below. then drag a graph and equation to represent each situation. indicate whether each of the relationships is proportional or non-proportional. edit : i got the right answer its attached

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)
