Use the given domain to find the range of the function: f(x)=−x3+x2+5, D={−2, −1, 2}

marysya [2.9K]

Answer:

The range of the function is $R=\{17, 5, 1\}$ .

Step-by-step explanation:

Let $f(x) = -x^{3}+x^{2}+5$ . From Function Theory we must remember that the range of function corresponds to the set of images associated to each elemenf from domain. In this case, the function has a domain composed of three elements and we need to find the image of each element:

x = -2

$f(-2) = -(-2)^{3}+(-2)^{2}+5$

$f(-2) = 8+4+5$

$f(-2) = 17$

x = -1

$f(-1) = -(-1)^{3}+(-1)^{2}+5$

$f(-1) = 1-1+5$

$f(-1) = 5$

x = 2

$f(2) = -(2)^{3}+(2)^{2}+5$

$f(2) = -8+4+5$

$f(2) = 1$

The range of the function is $R=\{17, 5, 1\}$ .

Look at the figure. Find the value of CG.

vladimir2022 [97]

Answer:

x = 6

Step-by-step explanation:

As before, ray BG is an angle bisector. This makes CG and AG equal.

4x - 16 = 2x - 4

2x - 16 = -4

2x = 12

x = 6

To check:

4(6) - 16 = 2(6) - 4

24 - 16 = 12 - 4

8 = 8
