Given :-

The roots of the function are 5 and -3 .

To Find :-

The Quadratic function .

Answer :-

The roots of the function are 5 and -3 . In general we can write the Quadratic function with roots π and ∆ as ,

$\sf\longrightarrow$ f(x) = ( x - π )(x-∆)

So on using this we have ,

$\sf\longrightarrow$ f(x) = ( x -5)( x -(-3))

$\sf\longrightarrow$ f(x) = (x-5)(x+3)

$\sf\longrightarrow$ f(x) = x(x-5)+3(x-5)

$\sf\longrightarrow$ f(x) = x² -5x +3x -15

$\sf\longrightarrow$ f(x) = x² -2x -15

Hence the required answer is x² -2x -15.

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is C

Step-by-step explanation:

The sample

Household Income

< $60,000 > $60,000

I would never purchase a newspaper subscription. 40 63

I might or might not purchase a newspaper subscription. 53 70

I would probably purchase a newspaper subscription. 65 32

I already purchase a newspaper subscription. 73 16

Generally the sample size is mathematically represented as

$n = 40 + 53 + 65+ 73 + 63 + 70 + 32+ 16$

=> $n = 412$

Generally the number of the sample with an income greater $60,000 is mathematically represented as

$N = 63 + 70 + 32 + 16$

=> $N = 181$

Generally the number of families with an income more than $60,000 who might or might not purchase a newspaper subscription is

$X = 70$

Generally the percentage of families with an income more than $60,000 who might or might not purchase a newspaper subscription is

$P(X) = \frac{70}{181} * 100$

=> $P(X) = 39\%$
