Answer:
<em>The required values are b=-6 and d=4</em>
Step-by-step explanation:
The graph corresponds to the function
We are required to find the values of b and d.
They can be found by using two points that are clearly visible on the graph. For example, the points (0,4) and (2,0) belong to the function. Substituting their values in the function:
Simplifying:
4 = d
d = 4
Now use the point (2,0):
Since d=4, and calculating
Simplifying:
Dividing by 4:
The required values are b=-6 and d=4
