Yes
Step-by-step explanation:
A function correlates elements from a set one and only one element from a different set. Think of a train timetable: you can't have the same train in two points at a given time.
An easy way to solve the problem is to take a ruler (or the edge of a sheet of paper, as long as it's straight) and scan the graph parallel to the Y axis. As long as you don't touch the graph more than once, it's a function (zero points is ok!)

Answer is $5. if the drink was $4 and the total was $39 then subtract 39-4 u get 35. then do 35/7 because there are 7 bars, and we wanna figure out of much THOSE where, thus is why we subtracted 4.
Answer:
18.67 m/s²
Step-by-step explanation:
a = ∆v/ t
a= v - u/t
a = 2.8 - 0 / 0.15
a = 2.8 / 0.15
a = 18.67 m/s²
For 2) and 4), check the picture below
that's the "secant segments from external point" theorem... and that's just an example... so... use that for those
now, for the other two, you'd want to post them separately, one at a time, easier to track and revise
