Change these equations into function form.

Question

Write these equations in function form. Please explain.

 

1)  y+10x= 3

2)  y - 13=4x

3) 8x + y - 4= 0

4) 4y - 4x + 4=0

5)  3y - 9x= 27

6) 16 + 2y= 18x

7) 24 - 4y= 8x

Answer 1

In each case, just SOLVE FOR y, then re-label it f(x).  Or if you feel frisky, label the functions with other letters, but not x!
