The vertex form of all expressions is given below.
We have given that the expressions
We have to write the function in vertex form.
<h3>What is the vertex form of the equation?</h3>
The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Therefore the first equation

it can be written as

The second equation can be written as

vertex for is,

Answer:
In year 1986 the average cost of car is $12,000
Step-by-step explanation:
Cost function:
C = 30.5t² + 4192
Cost = $12,000
Find:
Year
Computation:
C = 30.5t² + 4192
12,000 = 30.5t² + 4192
t = 16 year
So,
Year 1970 + 16 year
1986
So, In year 1986 the average cost of car is $12,000
