Comments (12) on “8) Does the table show a function? *”
Part A:
The given values in form of ordered pairs are: (2,1), (3,1), (4,-3), (3,-3)
A relation can be a function if one value of x is paired with exactly one value of y. In this case, x value of 3 is paired with two y values 1 and -3. So this relation is not a function.
Part B:
f(h) = 15h + 5 f(8) can be found by substituting h=8 in above equation. So, f(8) = 15(8) + 5 = 125 h represents the number of hours and f(h) represents the earnings of Kylie. So f(8) shows that Kylie earned $125 from 8 hours of work in the cafe
Part C:
For r hours of work, we can write: f(r) = 15r + 5 So, the ordered pair can represent this relation as: (r, f(r)) or (r, 15r+5)
if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
A function will not have any repeating x values...u can have repeating y values, just not the x ones. Now look at ur x values (2,3,4,5)...no repeating numbers...their all different...means this IS a function.
f(h) = 15h + 5 f(8) = 15(8) + 5 f(8) = 120 + 5 f(8) = 125 <== this is basically saying, that for working 8 hrs, Kylie earned $ 125.

So,
f(8) = 15(8) + 5 = 125
h represents the number of hours and f(h) represents the earnings of Kylie. So f(8) shows that Kylie earned $125 from 8 hours of work in the cafe
Part C:
For r hours of work, we can write:
f(r) = 15r + 5
So, the ordered pair can represent this relation as:
(r, f(r))
or
(r, 15r+5)
{(2, -3),(3,-3),(1,4),(9,2)}

answer:
try putting each question by it's self
step-by-step explanation:
The answer will be 45 because once you divide all the numbers you will get 45
Hope this helps

f(h) = 15h + 5
f(8) = 15(8) + 5
f(8) = 120 + 5
f(8) = 125 <== this is basically saying, that for working 8 hrs, Kylie earned $ 125.
f(r) = 15r + 5input (r) = 3
f(3) = 15(3) + 5
f(3) = 45 + 5
f(3) = 50output ...f(3) = 50
ordered pair is : (3,50)
A. No. A function must be single-valued, meaning there can only be one value of y for any given x.
B. f(8) = 32*8 +75 = 331
Read the definition:
f(8) is "the total cost in dollars for renting a boat for 8 hours"
