The negative sign will have an effect in terms of which way the graph opens up. Since the function starts off negatively the graph will open down, like an upside down U. Rather if the function started off positive I.e Y=x^2 the graph will open upwards like a upright U.
Answer:
C. y = 21x+90
Step-by-step explanation:
Let x be the number of hours. Each hour costs 21 dollars, so the cost of all the hours would be 21x. Then add a fixed fee of 90 to get C, y = 21x+90
