The roots of a quadratic function are x = -3 and x = 2/3. Which of the following would be the constant term of the equation in s
1 answer:
Answer:
-2
Step-by-step explanation:
Since the roots are known and the function is a quadratic function, we can write down the function:
y = (x+3)(x-2/3) since when the roots are plugged in, the function gives 0.
Standard form means that the function has to be expanded:
y = (x+3)(x-2/3) =
y =
The constant term is -2.

Answer:
Area covered by the fences will be 16.1 unit²
Step-by-step explanation:
Let the first parabola is represented by the function f(x) = 6x²
and second parabola by g(x) = x² + 9
point of intersection of the graphs will be determined when f(x) = g(x)
6x² = x² + 9
5x² = 9
x² = 1.8
x = ± 1.34
Now we will find the area between these curves drawn on the graph.
Area =

=
=
=
= 16.1 unit²
