= f(3) = 12
Therefore the value of f(14) is 12.

I don’t know if it’s right
Standard form of a quadratic f(x) = ax^2 + bx + c
In a quadratic function you find the vertex using the formula x = -b/2a; once you find the x value, substitute it into the equation and solve for y.
To know if a parabola opens up or down you look at the coefficient of the x^2 term. If it is positive, the graph opens up; if it is negative, the graph opens down.
Answer: 76 rows.
Step-by-step explanation:
The gardener has 5770 plants.
Now, suppose that he plants M rows of plants, such that each row has N plants on them
Then the total number of plants is M*N
And he wants to have the same number of rows that plants in each row, then:
M = N
Then the total number of plants is M*M = M^2
Now we know that he falls short by 6 plants, then we have the equation:
M^2 = his total number of plants + 6 plants
M^2 = 5770 + 6 = 5776
We can solve this for M, as:
M = √(5776) = 76
This means that the gardener wants to make 76 rows.
