The equation f(x) = 5x2 − 30x + 6 represents a parabola. what is the vertex of the parabola?

(−5, 281)
(5, −19)
(−3, 141)
(3, −39)

D.

Step-by-step explanation:

We have been given an equation . We are asked to find the vertex of parabola for our given equation.

We will use formula to find the x-coordinate of the vertex of parabola, then we will substitute the value of x-coordinate in our equation to find the y-coordinate of the parabola.

Therefore, the x-coordinate of the vertex of the parabola is 3.

Now let us substitute in our given equation to find the y-coordinate of the parabola.

So, the y-coordinate of the vertex of parabola is . The point represents the vertex of the parabola represented by our given equation and option D is the correct choice.

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4

the answer would be a 24
