Sever21 [200]4 years ago
3 0

Answer:

Part A: yes it is a function because every input value (x) produces only one output value (y).

Note: It is still a function if different x values produce the same y value, in this case, x=1 and x=-1 produce the same y value 1, but it is NOT a function if y=1 and y=-1 have the same x value x=1.  

Part B: when x=30: f(30)=17*30+50=560

if means that the cost of renting the truck for 30 hours is 560 dollars.

this help?

Please help me!
Sindrei [870]
Well, let's check if your inequality is true. We have to add the 3 scores up and divide them by 3 to know the average.

73 + 81 + 86 = 240
240 / 3 = 80

80%

That's true, now let's check 101.

73 + 81 + 101 = 255
255 / 3 = 85

85%

That's true.

Your inequality is correct.
