Answer:

Very similar to solving an equation.

Step-by-step explanation:

You have to use the properties of equality to "undo" each number and isolate the letter to one side.

How ever, if you are multiplying or dividing by a negative number, then the inequality must be reversed.

F(x)=1/2x+4 For R={5,6,7,8}

anzhelika [568]

Hey there!!

Remember : R = range and f ( x ) = y and y = range

R : { 5 , 6 , 7 , 8 }

( 1 ) 5 = 1 x / 2 + 4

... 5 - 4 = x / 2

... 1 = x / 2

... x = 2 = ( 2 , 5 )

( 2 ) 6 = x / 2 + 4

... 2 = x / 2

... x = 4 = ( 4 , 6 )

( 3 ) 7 = x / 2 + 4

... 3 = x / 2

... x = 6 = ( 6 , 7 )

( 4 ) 8 = x /2 + 4

... 4 = x/2

... x = 8 = ( 8 , 8 )

Hope my answer helps!
