How are the coordinates of the extreme value and the equation from part B in the form y=(x-h)^2-c related.
True [87]

The extreme value of y = (x - h)² - c is the vertex of the equation.

<h3>What are extreme values of a function?</h3>

The extreme values of a function are either the maximum or minimum values of the function.

<h3>The equation of a parabola in vertex form</h3>

The equation of a parabola in vertex form with vertex (h', k) is given by

y = a(x - h')² + k and its extreme values are

  • if a > 0  (h', k) is a minimum point and
  • if a < 0 (h', k) is a maximum point.

Since y = (x - h)² - c is the equation of a parabola in vertex form, comparing with y = a(x - h')² + k,

  • h = h'
  • -c = k and
  • a = 1.

So, the cooordinates of the vertex of y = (x - h)² - c is (h, -c).

Now, since a = 1 > 0, (h, -c) is a minimum point.

So, the extreme value of y = (x - h)² - c is the vertex of the equation.

Pls help I have no clue
suter [353]

Step-by-step explanation:

y-2 = - 3(x-3)

y - 2 =-3x +9

y -2 +2 = - 3x +9 +2

y = - 3x +11

To find the the coordinate

When x =0

y = - 3(0) +11

y= 11

When y = 0

0 = - 3x +11

Subtract 11 from both sides

-3x = - 11

x = 11/3

The y intercept is 11 so, one of your points will be at (0, 11) while the other will be at (11/3, 11).

Advocard [28]

Answer:

8

Step-by-step explanation:

finding the area is h x l x 1/2. The h is 4 and the l is also 4. That multiplied is 16. Multiply that by 1/2 and you get 8
