Which statement describes the domain of the function f (x) = StartFraction 3 x Over 4 x squared minus 4 EndFraction?

drek231 [11]

<em>The domain is the set of all real number except 1 and -1</em>

<h2>Explanation:</h2>

We have the following function:

$f(x)=\frac{3x}{4x^2-4}$

So the domain is the set of all x-values for which the function is defined. Since we have $4x^2-4$ in the denominator, then:

$4x^2-4\neq 0 \\ \\ \\ Factor \ out \ 4: \\ \\ 4(x^2-1)\neq 0 \\ \\ (x^2-1)\neq 0 \\ \\ \\ Difference \ of \ squares: \\ \\ (x-1)(x+1)\neq 0 \\ \\ \\ So: \\ \\ \\\boxed{x\neq 1 \ and \ x\neq -1}$

In conclusion:

<em>The domain is the set of all real number except 1 and -1</em>

Graph the equation y=−x²−8x−15 on the accompanying set of axes. You must plot 5 points including the roots and the vertex.

s2008m [1.1K]

Answer:

Plot these points

(-3,0)

(-5,0)

(-4,1)

(-2,-3)

(-6,-3)

Step-by-step explanation:

Let find the zeros of the equation.

We can factor this equation.

Factor out the -1.

$- 1( {x}^{2} + 8x + 15)$

Factor using AC method

$- 1(x + 3)(x + 5)$

Set all the terms equal to zero.

$x + 3 = 0$

$x + 5 = 0$

$x = - 3$

$x = - 5$

So our x intercepts are -3,0 and -5,0.

To find our vertex, apply the -b/2a.

$\frac{8}{ - 2} = - 4$

Then

Substitute-4 for x.

$y = - {4}^{2} - 8( - 4) - 15 = 1$

So our vertex is at (-4,1).

Find some other points like -2 and -6.

To find -2, substitute-2 into the quadratic.

$y = - ( { - 2}^{2}) - 8( - 2) - 15 = - 3$

So -2,-3.

Since y=-4 is the axis of symmetry

-6,-3

ELEN [110]

Answer:

He can buy 24 roses

Step-by-step explanation:

First, we subtract 3 from 21 to get 18. After that to get the price of each rose, we divide 21 by 0.75 to get 24.
