Answer:
Below 
Step-by-step explanation:
First we can go ahead and create a general equation for this polynomial 
Here are our roots : 
      x1 = - 3 
      x2 = -1 
      x3 = 1 
Now because this function extends from quadrant 4 to 3, we know that this has been reflected in the x-axis : 
      f(x) = - ( x + 3 ) ( x + 1 ) ( x - 1 )
However if we look closely you can see that the graph appears to "bounce" off certain roots. In this case it bounces off x = 1. This means that this root is an order of 2. It also has a weird looking curve on x = - 3 which means that this root is an order of 3. 
Our general equation will look like this : 
      f(x) = - ( x + 3 )^3 ( x - 1 )^2 ( x + 1 ) 
Now we need to sub in any point on the graph to solve for the <em>a </em>value. I'm just going to arbitrarily pick the y-intercept at ( 0 , -3 ) 
      - 3 = - a ( 0 + 3 )^3 ( 0 - 1 )^2 ( 0 + 1 ) 
      - 3 = - a (3)^3 (-1)^2 (1) 
      - 3 = - a (27)(1)(1) 
      - 3 = - a27 
      1/9 = a 
Here is our FINAL equation : 
      f(x) = - 1/9 ( x + 3 )^3 ( x - 1 )^2 ( x + 1 ) 
Hope this helps! Best of luck <3 
I would really appreciate a brainliest if possible :)
