Answer:

See below and attachment

Step-by-step explanation:

<u>Given function:</u>

  • y = -2(x - 3)² + 4

<em>The graph is attached and the axis of symmetry and all the required points plotted </em>

a) Axis of symmetry:

  • x = 3

b) It has no minimum as the leading coefficient is negative.

  • Maximum value is at vertex- the point (3, 4).
  • Maximum value is y = 4

c) and d) x - and y - intercepts already given in the question

e) Domain is all real numbers. x = ( -∞, +∞ )

Range is y = ( - ∞, 4]

Answer:

  h, j2, f, g, j1, i, k, l (ell)

Step-by-step explanation:

The horizontal asymptote is the constant term of the quotient of the numerator and denominator functions. Generally, it it is the coefficient of the ratio of the highest-degree terms (when they have the same degree). It is zero if the denominator has a higher degree (as for function f(x)).

We note there are two functions named j(x). The one appearing second from the top of the list we'll call j1(x); the one third from the bottom we'll call j2(x).

The horizontal asymptotes are ...

  • h(x): 16x/(-4x) = -4
  • j1(x): 2x^2/x^2 = 2
  • i(x): 3x/x = 3
  • l(x): 15x/(2x) = 7.5
  • g(x): x^2/x^2 = 1
  • j2(x): 3x^2/-x^2 = -3
  • f(x): 0x^2/(12x^2) = 0
  • k(x): 5x^2/x^2 = 5

So, the ordering least-to-greatest is ...

  h (-4), j2 (-3), f (0), g (1), j1 (2), i (3), k (5), l (7.5)

If AB=48 and BC=22, then AC=?
alexandr1967 [171]

If A, B and C are collinear, then

1) if B is between A and C:

AC = AB + BC

AC = 48 + 22 = 70

2) if C is between A and B:

AB = AC + BC

48 = AC + 22 |-22

AC = 26

3) if A is between B and C:

BC = AB + AC

22 = 48 + AC |-48

AC = - 26 < 0 FALSE

Answer:

if B is between A and C, then AC = 70

if C is between A and B, then AC = 26

Using the order of operations rule, solve the following: 12 ÷ 2 + 4 – 2 × 3 = ? A. 36 B. 0 C. 4 D. 24 Mark for review
AlexFokin [52]
<h2>Answer:</h2>

<u>The answer is </u><u>(C) 4</u>

<h2>Step-by-step explanation:</h2>

According to the rule of BODMAS

We will first do division then Multiplication then addition and in the last we do subtraction

So

12 ÷ 2 + 4 – 2 × 3 will be done as

= (12 ÷ 2) + 4( – 2 × 3)

= 6+4-6

= 4
