Answer:

I imagine you aren't using calculus, so:

A: the leading term is 1>0, so it opens upwards.

B. First coordinate of the vertex is -\frac b{2a}=-\frac42=-2, the second coordinate we'll find by replacing the value: f(-2)=(-2)^2+4(-2)-12 = 4-8-12=-16

C. Quadratic formula or if you stare at the equation long enough you can rewrite the equation as  f(x) = (x+6)\times(x-2). At this point the x intercepts are the zeroes of the function, or -6 and 2.

D. The y-intercept is the value of the function at 0, or the constant term: -12

E. The graph has a minimum since the curve opens upwards.

Please explain how to do and set up
In-s [12.5K]

A

using the Cosine rule in ΔSTU

let t = SU, s = TU and u = ST, then

t² = u² + s² - (2us cos T )

substitute the appropriate values into the formula

t² = 5² + 9² - (2 × 5 × 9 × cos68° )

   = 25 + 81 - 90cos68°

   = 106 - 33.71 = 72.29

⇒ t = \sqrt{72.29} ≈ 8.5 in → A
