Answer:
Step-by-step explanation:
The question tells us that;
Given F1 = ∑ m(0,2,5,7,9) and F1 = ∑ m(2, 3,4,7,8) find the minterm expression for F1+F2. State a general rule for finding the expression for F1+F2 given the minterm expansions for F1 and F2. Prove your answer by using the general form of the minterm expansion.

Answer:
Vertex form:
Standard form:
Step-by-step explanation:
A quadratic function in vertex form is where
is the vertex.
We are given .
Let's plug that in:
.
Now let's find .
We will use the -intercept
to find
.
So the function in vertex form is:
.
In standard form, we will have to multiply and combine any like terms.
Let's do that:
For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: total cost
We write the algebraic expression that models the problem.
We have then:
Simplifying we have:
Then, by the time the cost is equal to $ 300 we have:
From here, we clear the value of x.
Answer:
an algebraic expression for the problem is:
