If 48 square ; 68x The Power Of 4;x ;36Xpower Of 2 Are in Proportion Fond The Value Of x

ollegr [7]

According to question,

As $48x^{2}$ ; $64 {x}^{4}$ ; $x$ ; $36 {x}^{2}$ are in proportion, so,

$48 {x}^{2} = 64 {x}^{4} = x = 36 {x}^{2}$ {x ≠ 0}

(Simplification attached as image)

$= > \frac{12}{ {17x}^{2} } = \frac{1}{36x}$

$= > 17 {x}^{2} = 12 \times 36x$

$= > 17x = 432$ (Divided by 17 each side)

$= > x = \frac{432}{17}$

Hence, value of x is $\frac{432}{17}$

Which represents a quadratic function? f(x) = −8x3 − 16x2 − 4x f (x) = three-quarters x 2 + 2x − 5 f(x) = StartFraction 4 Over x

tatyana61 [14]

Answer:

$2.\ f(x) = \frac{3}{4}x^2 + 2x - 5$

Step-by-step explanation:

Given

$f(x) = -8x^3 - 16x^2 - 4x\\f(x) = \frac{3}{4}x^2 + 2x - 5\\f(x) = \frac{4}{x^2} - \frac{2}{x} + 1\\f(x) = 0x^2 - 9x + 7$

Which of the above is a quadratic function

A quadratic function has the following form;

$ax^2 +bx + c = 0 \ where \ a\neq 0$

So, to get a quadratic function from the list of given options, we simply perform a comparative test of each function with the form of a quadratic function

$1.\ f(x) = -8x^3 - 16x^2 - 4x$

This is not a quadratic function because it follows the form $f(x) = ax^3 + bx^2 + c$ and this is different from $ax^2 +bx + c = 0 \ where \ a\neq 0$

$2.\ f(x) = \frac{3}{4}x^2 + 2x - 5$

This function has an exact match with $ax^2 +bx + c = 0 \ where \ a\neq 0$

By comparison; $a = \frac{3}{4}\ b = 2\ and\ c = -5$

$3.\ f(x) = \frac{4}{x^2} - \frac{2}{x} + 1$

This is not a quadratic function because it follows the form $f(x) = \frac{a}{x^2} + \frac{b}{x} + c$ and this is different from $ax^2 +bx + c = 0 \ where \ a\neq 0$
