Hello!
Recall that the equation of an exponential graph is:
We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:
Solve for b by plugging in another point on the graph:
Write the final equation:
Answer:
Step-by-step explanation:
Given
See attachment for grid
Required
Find c and d
From the attachment, we have:
--- Point on A
--- Corresponding point on B
When A is reflected across the x-axis, the rule is:
So, we have:
Next, is to calculate the translation from to
This is calculated using:
and
So, we have:
---- i.e. Shift by 6 units to the left
--- i.e. Shift by 1 unit down
