<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’.

Step-by-step explanation:
The number of tubes can be found from an inequality that relates the number of square inches that can be painted to the number of square inches that must be painted.
Let t represent the number of tubes.
1400t ≥ 3672 . . . . . the number of tubes that will paint at least 3672 in²
t > 2.623 . . . . . divide by 1400
If only whole numbers of tubes are available, then ...
3 tubes are needed to paint the ramp.
The Pythagorean Theorem works for all RIGHT triangles.
