Find the range of f(x) = 3x - 5 for the domain {-1.5, 2, 4} a) {-8, 10, -1, -1} b) {-9.5, 1, 7} c) {8, 10, 1, 1} d) {9.5, -1, -7}

For this case we have the following function:

To find the values of the range of the function, we substitute the values of the domain.

We have then:

For x = -1.5:

For x = 2:

For x = 4:

Therefore, the values of the range are given by:

{-9.5, 1, 7}

the range of for the domain {-1.5, 2, 4} is:

B) {-9.5, 1, 7}

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
