Question

Which of the following would illustrate a quadratic relation between the dependent and independent variables when graphed?

A. a graph of the area of a circle vs. its radius r (a = πr^2)

B. a graph of the equation a = 1/b

C. a graph of distance vs. time for a car moving at constant speed

D. a graph of mass of water vs. the volume of water in a drinking glass


**I'm pretty sure it wouldn't be C right? because constant would be a linear line? thank you!! :D

Answer 1

^&%@&^#%&^@%&^!%&!*^@&!! >.< i have no idea what this is - sorry ;~; wish i could help yuh

Answer 2

do you know what a "quadratic equation" is?

Answer 3

haha it's physics! the subject bar wasn't working for me so I just posted it here! thanks though @arabpride :)

and it curves right? @jdoe0001 :)

Answer 4

well.. nope.... QUADratic means the function is of a 2nd degree

Answer 5

ohhh okay :)

Answer 6

lolz - yah havn't taken physics <repeated facewacks> x'D

Answer 7

what does that mean exactly though? @jdoe0001 :/

and haha no worries @arabpride :)

Answer 8

\(\large \begin{array}{llll}
dependent&{\color{blue}{ degree}}\\
\downarrow &\ \downarrow \\
area = \pi &r^{\color{blue}{ 2}}\\
&\uparrow \\
&independent
\end{array}\)

Answer 9

A'Ight Good Luck ^-^*

Answer 10

ohh okay, so @jdoe0001 it would be choice A? :O

and thanks @arabpride ! :D

Answer 11

yes

Answer 12

B is a LINEar function
C is a LINEar as well
D has volume, thus 3 units, thus a 3rd degree expression

Answer 13

ahh okay thank you so much!! :D
