Answer:

Step-by-step explanation:
Vertex form of a quadratic function:
where:
- (h, k) is the vertex
- a is some constant
If the vertex is at the origin, then (h, k) = (0, 0)


Comparing this with the answer options suggests that the function with a vertex at the origin is 
If you subtract 25 from 12 you will get 13 cents. So you will get back 1 dime and 3 pennies.

Jane is given a $100 gift to start and saves $35 a month from her allowance.
After 1 month, Jane has saved
After 2 months, Jane has saved
After three months, Jane has saved
and so on
In general, after x months Jane has saved
This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.
Step-by-step explanation:
The answer to this equation would be 3.
