Write a formula for quadratic function if its graph has the vertex at point (0,6) and passes through the point (−1,−2).
d1i1m1o1n [39]

Answer:

y = - 8x² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (0, 6), thus

y = a(x - 0)² + 6, that is

y = ax² + 6

To find a substitute (- 1, - 2) into the equation

- 2 = a(- 1)² + 6, that is

- 2 = a + 6 ( subtract 6 from both sides )

- 8 = a

y = - 8x² + 6

Please help with #19!
ikadub [295]

Answer:

a) yes

b) 2560

Step-by-step explanation:

An exponential function has a common ratio between points uniformly spaced. Here, the data points are 10 years apart.

The ratio of the first two values is 4000/5000 = 0.8.

The ratio of the next two values is 3200/4000 = 0.8.

These ratios are the same, so the data is consistent with an exponential function.

The common ratio can be used to predict the next value. The next value is predicted to be ...

  3200 × 0.8 = 2560

What is the answer to this?<br><br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B-3%28x-10%29%7D%7B4%7D%2B2%3D11" id="TexFormula1
Mila [183]

Step-by-step explanation:

=== [ -3(x-10)/4] + 2 = 11

==> [( -3x + 30 + 8)/4 = 11

==> -3x = 44 - 38

==> -3x = 6

==> -x = 6/3

==> x = -2
