Question

(Due soon, please hurry!)

If 8 is an element in the domain of f(x) = 5x-18 / 2, what is the corresponding element in the range?

Answer 1

`\ \ \sf\longmapsto f(x)=(5x-18)/(2)`

Now

`\ \ \sf\longmapsto f(8)=(5(8)-18)/(2)`

• Simplify

`\ \ \sf\longmapsto f(8)=(40-18)/(2)`

`\ \ \sf\longmapsto f(8)=(22)/(2)`

`\ \ \sf\longmapsto f(8)=11`

Answer 2

The corresponding element in the range is ~

`\boxed{11}`

`\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}`

Just plug the value of element in domain in the given function ~

we get ~

• 
  `f(x) = (5x - 18)/(2)`

• 
  `f(8) = ((5 * 8) - 18)/(2)`

• 
  `f(8) = (40 - 18)/(2)`

• 
  `f(8) = (22)/(2)`

• 
  `f(8) = 11`

hence , the corresponding element in the range is ~ 11
