x+y=3 y=3-2x so x+3-2x=3 so x=0 0+y=3 so y=3
x5 You have x*x*x*x*x just add up the amount of x's you have and put it after as an exponent Example: 3*3*3*3=34 y*y*y*y*y*y=y6

Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3
