9. What is the vertex of the function? f(x) = 3x² - 8x + 10

Delvig [45]

Answer:

The vertex of the function is (1.333, 4.667)

Step-by-step explanation:

1. Calculate -b / 2a. This is the x-coordinate of the vertex.

2. simply plug -b / 2a into the equation for x and solve for y.

$Y = 3x^{2} - 8x + 10\\Compare with the form of y = ax^{2} + bx + c\\So that means a = 3, b = -8, and c = 10.$

Calculate -b/2a:

$X = -(-8)/2(3)$

$X = 8/6$

This is equal to 1.33 recurring

Plug 8/6 for x and solve for y:

$Y = 3x^{2} - 8x + 10$

$Y = 3(\frac{8}{6})^{2} - 8(\frac{8}{6}) + 10$

$Y = \frac{48}{9} - \frac{64}{6} + 10\\$

This is equal to 4.66 reccuring.

y varies directly with x,

so y=kx

-34=k×2

k= -17

85= -17× X

X= -5
