Answer:
The standard form of the parabola is 
Step-by-step explanation:
The standard form of a parabola is
.
In order to convert 
into the standard form, we first separate the variables:
we now divided both sides by 2 to remove the coefficient from 
and get:
.
We complete the square on the left side by adding 3 to both sides:
now we bring the right side into the form 
by first multiplying the equation by 
:
and then we multiplying both sides by 
to get
.
Here we see that
Thus, finally we have the equation of the parabola in the standard form:
We will see that the exponential decay function is:
f(x) = 175*(0.8)^x

How to find the exponential decay?</h3>
The general exponential decay is:
f(x) = A*(1- r)^x
Where:
- A is the initial value.
- r is the rate of decay in decimal form.
- x is the variable, in this case is the time.
Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.
20%/100% = 0.2
Replacing that in the exponential function, we get:
f(x) = 175*(1 - 0.2)^x
f(x) = 175*(0.8)^x
