Find the domain of the function j(x)= 3x -5 given the range (-7 -1 0 , 10)


Please help I am super bad at math

Respuesta :

Answer:

Solution is five or three ; y =-5

Step-by-step explanation:

0=3x-5

y=-5

3 times 0 minus 5 and then multiply the numbers

J(0)=0-5 then remove 0

Answer:

see explanation

Step-by-step explanation:

To find the domain given the range, equate f(x) to each value from the range and solve for x, the domain.

3x - 5 = - 7 ( add 5 to both sides )

3x = - 2 ( divide both sides by 3 )

x = - [tex]\frac{2}{3}[/tex]

3x - 5 = - 10 ( add 5 to both sides )

3x = - 5 ( divide both sides by 3 )

x = - [tex]\frac{5}{3}[/tex]

3x - 5 = 10 ( add 5 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

Domain is { - [tex]\frac{5}{3}[/tex], - [tex]\frac{2}{3}[/tex], 5 }
