Given the equation:

Let's find the values of a and b using the given graph.
Since the curve faces up, the value of b will be less than 1.
We have:
Vertical Asymptote at x = -4
Equate to zero:
x + 4 = -4 + 4
x + 4 = 0
Thus, we have:

Now, take the point:
(x, y) ==> (5, -4)
Input the values for x and y, then solve for b:
Where:
x = 5
y = -4

Therefore, the equation is:

• The value for a is , 4
,
• The value for b is , -2
