Answer:
Whats the question
Step-by-step explanation:
Yes, you are correct, it is A!
Recall the pencil line test, which is where you go across the x axis (the graph horizontally) and see if the pencil touches any two points at the same time. If it does, then the graph is not a function.
Point being: since question a has a bunch of y values on top of one x value, the pencil would inevitably touch multiple at the same time, hence why it is easy to tell that it is not a function! Hope this helps :)
Answer:
height = 15 inches
Step-by-step explanation:
the volume (V) of a cylinder is calculated as
V = Ah ( A is the base area and h the height )
given V = 1650 and A = 110 , then
1650 = 110h ( divide both sides by 110 )
15 = h
Answer:
No
Step-by-step explanation:
To obtain the inverse function
let y = f(x) and rearrange making x the subject, that is
y = 3x + 1 ( subtract 1 from both sides )
y - 1 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) =
