You need to know what X is equivalent to. in this EXAMPLE I will use 2

3(2 squared) + 5(2) - 7

3(4) + 10-7

12 + 10 - 7

22 - 7 = 14

the answer is 14  IF X EQUALS 2

X might not equal two in your case

Sveta_85 [38]

Answer: y = 25x + 50

Explanation: the total cost if the rental is a linear function of the number of days of the rental (x). Each day costs $25, so that is the slope of the line. Since there is also a one-time fee, independent of the number of days, this amount $50 represents a vertical shift of the line on the graph, by 50. y=25x+50 is an algebraic expression of that.
