The function modeled by the equation f(x) = 3x + 4 What is the range of function when domain is \ -2,3,5\ \ -6,19,29\ \ 20,19,29\ { 10,19,29\ \ 2,11,29\

The range are

(-2, 13 , 19)

(-14, 61, 91)

(64, 61, 91)

(34, 61, 91)

(10, 34, 91)

Step-by-step explanation:

f(x) = 3x + 4 

Substitute the domain into the function above.

when domain are \ -2,3,5\

F(-2) = 3(-2) + 4 = -2

F(3) = 3(3) + 4 = 13

F(5) = 3(5) + 4 = 19

Range = -2, 13 , 19

When domain are \ -6,19,29\

f(x) = 3x + 4

F(-6) = 3(-6) + 4 = -14

F(19) = 3(19) + 4 = 61

F(29) = 3(29) + 4 = 91

Range = -14, 61, 91

When domain are \ 20,19,29\

f(x) = 3x + 4

F(20) = 3(20) + 4 = 64

F(19) = 3(19) + 4 = 61

F(29) = 3(29) + 4 = 91

Range = 64, 61, 91

When domain are 10,19,29\

f(x) = 3x + 4

F(10) = 3(10) + 4 = 34

F(19) = 3(19) + 4 = 61

F(29) = 3(29) + 4 = 91

Range = 34, 61, 91

When domain are \ 2,11,29

f(x) = 3x + 4

F(2) = 3(2) + 4 = 10

F(11) = 3(11) + 4 = 34

F(29) = 3(29) + 4 = 91

Range = (10, 34, 91)

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
