Answer: The number of ceral boxes per day.
Because the slope will be [rise of the grah of the model function] / [run of the graph of the model function].
rise = [increase in the number of cereal boxes sold]
run = [days elapsed ]
rise / run = number of cereal boxes sold per day

Answer:
x=18
Step-by-step explanation:
ok, so you mulityply base and hieght then divide by 2
your base is 6 and your height is 6
6x6=36
36/2=18

<u>Answer:</u>
The value of f(x) =
when x=3 is 19, hence the correct option is ‘d’.
<u>Solution:</u>
A two degree polynomial equation is given in the question.
The equation is:

We need <em>to find the value of f(x) when the value of x is 3.
</em>
To solve a question like this we have to substitute the given value of x in the given equation and then simplify it.
Now let's substitute the value of x in the given equation.

First we square the number 3 and then multiply it with 2 and then add 1.
This is done because of the BODMAS rule, in which multiplication is given higher preference as compared to addition.
On solving the equation we get,
F(x)=2×9+1
F(x)=18+1
F(x)=19.
Therefore the value of f(x) when x=3 is 19.
Hence the correct option is ‘d’.
