Joyce sells books for 101010 dollars per book. She spent 454545 dollars to rent the building where she's selling. The profit Joyce makes can be modeled by the equation f(x)=10x−45f(x)=10x-45f(x)=10x−45. What is the domain and range of this equation for Joyce to make a profit?
Domain: [5,∞)[5, \infty)[5,∞)
Domain: [4,∞)[4,\infty)[4,∞)
Range: [5,∞)[5,\infty)[5,∞)
Range: [0,∞)[0,\infty)[0,∞)
Type a concept, like “slope” or “photosynthesis”.
