The amount of energy a microwave oven uses (in the form of electricity) is given by the function f(x)=5x+9,f(x)=5x+9, where xx is the amount of time the microwave is turned on. The amount of energy the microwave puts out is modeled by the function g(x)=−x2+3x+1,g(x)=−x2+3x+1, where xx is the amount of time the microwave is turned on. What is the difference between the amount of energy the microwave uses and the amount it puts out? f(x)=x2−8x−10f(x)=x2−8x−10 f(x)=−x2−2x−8f(x)=−x2−2x−8 f(x)=x2+2x+8f(x)=x2+2x+8 f(x)=−x2+8x+10
