First, the graph is a parbole, this is a square function, so it can not be the option a) because it is a linear function.

Second, the vertix of the parabole is the point (0,3), so use the general vertex form of the parabole:

y = A(x - h)^2 + k, where h and k represent the vertex (h,k).

So, the form of the funtion is y = A (x-0)^2 - 3 = Ax^2 - 3

Now, you also know that the roots of the parabole are close to -1 and 1 but they are not those exact value.

So, find the roots for any of the possible options:

b) f(x) = 2x^2 - 3 = 0 => 2x^2 = 3 => x^2 = 3/2 => x = +/- √(3/2) ≈ +/- 1.22

That is a very plausible answer

c) f(x) = (1/2)x^2 - 3 = 0 => x^2 = 2*3 = 6 => x = +/- √6  ≈ +/- 2.45, which is very far from the roots shown on the graph.

3) f(x) = x^2 - 3 = 0 => x^2 = 3 => x = +/- √3 ≈ +/- 1.73, which is not so close to +/- 1.

So, the answer is the option b) f(x) = 2x^2 - 3

Will give Brainliest!! pleases help, math.
oee [108]

Answer:

a = sqrt(b^2 + c^2 - 2bc cosA) = sqrt(13^2 + 6^2 - 2 * 13 * 6 * cos 50) = sqrt(169 + 36 - 156 cos 50) ≈ sqrt(205 - 100.3) ≈ sqrt(104.7) ≈ 10.2

a ≈ 10.2

c / sin C = a / sin A

sin C = c sin A / a = 6 sin 50 / 10.2 ≈ 0.4491

C = arcsin(0.4491) ≈ 26.7

C ≈ 26.7°

B = 180 - A - C ≈ 180 - 50 - 26.7 ≈ 103.3

B ≈ 103.3°
