We have the function 
and we want to find a function that has the same y-intercept than the previous function.
First, let's find the y-intercept by subtituting 0 for 'x'.
Now that we found that y-intercept =-3, any lineal function of the type: 
will have the same y-intercept. Where 'a' can take all the real values.
Also, any quadratic function of the type: 
will have the same y-intercept. Where 'a' and 'b' can take all the real values.
Area is length times width so it is 3 times 3 since a square sides are all the same
The side is 8 feet = 8*12 inches = 96 inches
Plants are needed if they are to be spaced 8 inches apart around the outside of the bed
96/8 = 12 ... so we need 12 plants on each side, please note it is including the corners.
If we not incluse corner, the flowers will be 10 each side.
Means total flower : 10 * 4 (each side) + 4(corner)
The total needed is 44 plants. : Answer
Hope that will help :)
