First do 5times 6 equals 30 then add 2 that gives you 32 the next step is to divide by 8 this will give you a final answer of 4
The exponential function is 
<h3>How to determine the equation?</h3>
An exponential function is represented as:
y = b^x
Where b represents the base.
The base is given as:
b = 12
So, we have:
y = (12)^x
It is vertically compressed by a factor of 1/8.
So, we have:
y = 18(12)^x
When reflected across the y-axis, we have:

The horizontal asymptote is y = 2.
So, we have:

It passes through the point (-3, 4).
So, we shift the function to the right by 4 units

Express as a function

Hence, the exponential function is

Answer:
Here a = 20,, b= 8
Step-by-step explanation:
Using Pythagoras theorem,
a^2 + 15^2 = 25^2 ,, b^2 + 6^2 =10^2=100
