A 2-column table with 6 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2, 3. The second column is labeled f of x with entries negative 10, negative 8, negative 6, negative 4, negative 2, 0.
Which is an x-intercept of the continuous function in the table?

(0, –6)
(3, 0)
(–6, 0)
(0, 3)

Step-by-step explanation:

The given table is

x    f(x)

-2   -10

-1    -8

0    -6

1     -4

2    -2

3    0

Remember, x-intercept has the form where is a real number. In other words, x-intercept are points with a null y-coordinate.

As you can see in the given table, the x-intercept is at .

Therefore, the right answer is the second choice.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

pi x^2

step-by-step explanation:

pi times x squared
