<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’.
Answer:
Area of a triangle formula is 1/2 x base x height
Area of the garden = 1/2 x 25 x 10 = 125 square feet.
1 bag covers 10 square feet, divide total area by 10"
125 / 10 = 12.5
