17. Consider the nonhomogeneous equation: y" + by' + y = g(x) where b is a real constant. The following questions refer to your guess for yp using the method of undetermined coefficients. Do not solve for the coefficients. (a) If g(x) = 3x – 1, what is the first guess for y,? (b) Identify the value of b if g(x) = 7 sin x and you need your second guess for yp. What is that guess? (c) Identify the value of b if g(x) = 18e" and you need your third guess for Yp. What is that guess?

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
