PLEASE ANSWER! Given the functions f(x) = x2 + 6x - 1, g(x) = -x2 + 2, and h(x) = 2x2 - 4x + 3, rank them from least to greatest

Ratling [72]

Answer:

he rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.

Step-by-step explanation:

A quadratic equation is given by:

$ax^2+bx+c =0$

Here, a, b and c are termed as coefficients and x being the variable.

Axis of symmetry can be obtained using the formula

$x = \frac{-b}{2a}$

Identification of a, b and c in f(x), g(x) and h(x) can be obtained as follows:

$f(x) = x^2 + 6x - 1$

⇒ a = 1, b = 6 and c = -1

$g(x) = -x^2 + 2$

⇒ a = -1, b = 0 and c = 2

$h(x) = 2^2 - 4x + 3$

⇒ a = 2, b = -4 and c = 3

So, axis of symmetry in $f(x) = x^2 + 6x - 1$ will be:

$x = \frac{-b}{2a}$

x = -6/2(1) = -3

and axis of symmetry in $g(x) = -x^2 + 2$ will be:

$x = \frac{-b}{2a}$

x = -(0)/2(-1) = 0

and axis of symmetry in $h(x) = 2^2 - 4x + 3$ will be:

$x = \frac{-b}{2a}$

x = -(-4)/2(2) = 1

So, the rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.

HELP PLEASE I HAVE A TEST TOMORROW AND NEED TO STUDY scale drawing of a school bus has a scale of 1/2 inch to 5 feet. if the len

kakasveta [241]

Answer: 45

Step-by-step explanation:

There are 9 half inches in 4 1/2 so that means you multiply 9 by 5 because for every 1/2 inch on the drawing is 5 feet in real life so you would get 45

Which value of x satisfies the inequality x+3<20 ? 17 19 21 23

AVprozaik [17]

Neither actually, if 20 is bigger than x+3 nothing + 3 will give you something under 20. You could actually use 17 + 3 but, then again the sign would have to be = rather than < .

17 + 3 = 20
19 + 3 = 20
21 + 3 = 24
23 + 3 = 26

Y2+3y−4divided by y^2−5y+4

EleoNora [17]

Answer:

(y+4)

----------------

(y-4)

y cannot equal 4 or 1

Step-by-step explanation:

y^2 +3y -4

-----------------

y^2 -5y +4

I will factor the numerator and the denominator

(y+4) (y-1)

----------------

(y-4) (y-1)

The factors that must be excluded must be determined before we cancel

y cannot equal 4 or 1 because that would make the denominator go to zero

Cancel y-1 from the numerator and denominator

(y+4)

----------------

(y-4)
