Q. What is (f+g)(x)?f(x)=5x+3g(x)=−3x2Write your answer as a polynomial or a rational function in simplest form.______
Identify Formula: Identify the formula for (f+g)(x). The correct formula is (f+g)(x)=f(x)+g(x).
Substitute Values: We have f(x)=5x+3 and g(x)=−3x2. Substitute these values into the formula to get (f+g)(x)=(5x+3)+(−3x2).
Simplify Equation: Simplify the equation (f+g)(x)=(5x+3)+(−3x2) to find (f+g)(x).(f+g)(x)=−3x2+5x+3Note that we have rearranged the terms in descending order of the power of x.
