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.

Answer:
$2.25
Step-by-step explanation:
Let "b" be the price of 1 brownie and "c" the price of 1 cookie.
At a bake sale, a student spent $11.00 buying 3 brownies and 5 cookies. Symbolicaly,
3 b + 5 c = 11.00   [1]
His friend spent $3.95 buying 1 brownie and 2 cookies. Symbolicaly,
1 b + 2 c = 3.95
b = 3.95 - 2c   [2]
If we replace [2] in [1], we get
3 (3.95 - 2c) + 5 c = 11.00
11.85 - 6c + 5c = 11.00
c = 0.85
If we replace c = 0.85 in [2], we get
b = 3.95 - 2 (0.85) = 2.25
