Graph: http://prntscr.com/cjgzb6



A. {-4, 0}

B. {5, 1}

C. {-4, 2}

D. {2, 4}

Answer 1

the zeroes are the points on the x axis where the graph intersects.

Answer 2

to find the zeros use the famous quadratic formula
\[\frac{ -b \pm \sqrt{b^2 - 4ac} }{ 2a }\]

Answer 3

The points where the graph cuts the x axis

Answer 4

they are called the zeroes because this is where the function has a value of zero.

Answer 5

More precisely the x coordinate of the points where graph cuts the x axis

Answer 6

ok in that case would my answer be {-4,2}?

Answer 7

Right

Answer 8

yes

Answer 9

no clue bc i haven't looked at it anyway lol
