Does this graph represent a function? Why or why not? A. No, because it is not a straight line.
B. Yes because it passes the vertical line test.
C. No because it fails the vertical line test.
D. Yes because it passes the horizontal line test.

B. Yes because it passes the vertical line test.

Explanation:

Since it is not possible to draw a single vertical line through more than one point on the red curve, this means that the curve passes the vertical line test. This means that any input x leads to exactly one output y. So that's why we have a function here.

Side note: The function doesn't pass the horizontal line test, so this function is not one-to-one.

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
