Function 1:
For the given table

you can plot the graph of the function (see first attached diagram). This function is linear and has equation f(x)=3x+4.
Function 2:
For the given function f(x)=-2x+3 you can create a table

and plot the graph (see second attached diagram).
Function 3:
For the given graph of the function, you can find the function:

Thus, the equation of the function 3 is 
The table will take a look

Answer:
