Which graph represents a function

Mathematics
1 answer:
ICE Princess25 [194]3 years ago
3 0

Answer:

the bottom left one (the graph that looks like a circle) is not a function, but the other ones are.

Step-by-step explanation:

A function is defined so that for every x value within a function has a y value.  This means that an x value CANNOT have more than one y value.  The bottom right one has two y values for almost every x value within the domain.  The top ones are functions, because all x values have only 1 y value (a discontinuous function is still a function!)  And the bottom right is too.

rosijanka [135]
<h2>Answer:37 paintings of $50 and 15 paintings of $75</h2>

Step-by-step explanation:

Let x be the number of paintings Ella sells for $50.

Let y be the number of paintings Ella sells for $75.

Profit made through $50 paintings is 50x

Profit made through $75 paintings is 75y

So,total profit is given by 50x+75y

It is given that total profit is $2975

So,50x+75y=2975      ..(i)

Given that the total number of prints is 52

So,x+y=52      ..(ii)

using (i) and (ii),

50x+75(52-x)=2975\\50x+3900-75x=2975\\25x=925\\x=37

y=52-x=52-37=15
