Question

when give a graph of a quadratic function the questions asks you for zeros what are zeros

Answer 1

zeros is the value of x when the equation is equal to zero

Answer 2

for example
what are the zeros of
x^2+4x+4=0
(x+1)(x+3)=0
x=-1 x=-3

Answer 3

click "good answer" if you are contented

Answer 4

One other word is "roots", where the graph cross the x axis, and where the equation take the value 0.

Answer 5

If the graph of a quadratic function is given, it will be of parabolic shape

zeros are the points at which it intersects the x-axis

Answer 6

so is it the point where it intersects or zeros is the value of x when the equation is equal to zero

Answer 7

zero of a quadratic equation is the value(s) of x, these r given by the points where graph cuts x -axis ....

see the attached file. in this the two red points on the x-axis are the zeros of the quadratic function

Answer 8

If the quadratic function is equal to zero, it will be a quadratic equation

Answer 9

Where the function touches X axis ( need not cross it)

Answer 10

is it clear now ???????

Answer 11

I need 1 answer im getting like 5 different

Answer 12

if u have to calculate the zeros, then you have to equate the quadratic function = 0 to get the zeros.

if you plot a graph, then the point(s) where the graph touches or cuts the x-axis gives the zeros of the function

Answer 13

i think he needs a one sentence conlusion

Answer 14

is it clear now???

If you keep looking at answers from various people u will get confused.

Answer 15

*conclusion

Answer 16

i still dont get it sorry but what is the answer is it just a point that touches the x axis?

Answer 17

The graph of a quadratic function is a parabola whose axis of symmetry is parallel to the y-axis. here is a definition from wikipedia but i think it is not a good idea to copy this.

Answer 18

As I said before, if u r given a graph, then the point(s) where the graph touches or intersects the x-axis, gives the zeros of the quadratic function

a Quadratic function can have no real zeros i.e no zero -- In this case the graph will not even touch the x-axis

If it has two equal zeros then its tip will just touch the x-axis at one point

If it has two distinct zeros then it will cut the x-axis at two places as shown in the file that i attached

Answer 19

thanks for the medal.

for clear picture, attaching a paint file that i made for you, hope it makes my points more clear
