What multiplies to -4 and adds up to 7?

devlian [24]

The two numbers are (7+ sqrt(65))/2 and (7- sqrt(65))/2

(7+ sqrt(65))/2+ (7- sqrt(65))/2= 7
(7+ sqrt(65))/2* (7- sqrt(65))/2)= -4.

Hope this helps~

QUESTION 16<br> What is the absolute value of -72?

11Alexandr11 [23.1K]

The absolute value of -72 is 72.

Absolute value is essentially just making the number given positive.

If the given number is already positive then the absolute value is the same as the original number

Hope this helped!

The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function? The domain is all real n

dedylja [7]

Answer:

The domain is all real numbers. The range is {y|y ≤ 16}

Step-by-step explanation:

we have

$f(x)=-x^{2}-2x+15$

This is a the equation of a vertical parabola open downward

The vertex is a maximum

The vertex is the point (-1,16)

see the attached figure

therefore

The domain of the function is all real numbers ----> interval (-∞,∞)

Te range of the function is

$y\leq 16$

All real numbers less than or equal to 16 ----> interval (-∞,16]

construct a polynomial function with the stated properties. third degree with zeros of -2,-1, and 3 and passes through the point

AfilCa [17]

Answer:

$f(x) = - (x + 2)(x + 1)(x - 3)$

Step-by-step explanation:

Let f(x) be the 3rd degree polynomial function.

The roots of this function are:

x=-2, x=-1 and x=3.

The factored form is:

$f(x) = a(x + 2)(x + 1)(x - 3)$

This equation passes through (2,12)

This implies that;

$a(2 + 2)(2+ 1)(2 - 3) = 12 \\ - 12a = 12 \\ a = - 1$

The polynomial function is

$f(x) = - (x + 2)(x + 1)(x - 3)$
