Y^2=4-x^2 determine whether the equation defines y as a function of x

Yes , taking root on both sides we have y = √(4-x^2) so y is dependant on x and x only..so y is a function of x .

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

5 + 8 +7 + 4 + 0 +1 = 25
