K OOOOOGOGO Function notation provides us with a convenient way of in with a function or functions. Examples: y = 5x + 3 - y =f (x) Write the equation y = 5x + 3 in the form x = f (y) x = OK - x =f(y) d = 3a + 4b - c - d = f (a, b,c) Write the equation d = 3a + 4b - c in the form b = f(a, b, c) b = * " - b =f (a, b, c) -5 x= - x=f() 2y + 7 -5 Write the equation x = in the form y = f (x) 2y +7 y = x " - y =f(x)
