At a restaurant, diners eam 1 point for every $2 they spend, plus 25 bonus points on their first meal. Function f represents the number of polnts
earned as a function of the total amount spent x. Which function represents the total amount spent as a function of the number of points
earned?

Step-by-step explanation:

We know it can't be the first two because they don't get 2 points for every $1 spent, so it has to be f(x) = 0.5x + something. That something has to be 25 because they get 25 bonus points on their first meal, so the answer has to be f(x) = 0.5x + 25. Hope this helps!

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
