Name _________________________________ Period_________ Date________________Writing one Equation in Function form (page 1) one equation is in function kind when that is resolved for y. (This form will be useful when graphing a straight equation.) because that example, 2 x + y = 8 is no in role form. However, we can easily rewrite the in function form by individually 2x indigenous both political parties of the equation: y = −2 x + 8 is duty form. Examples: compose the equations in role form.
