Someone please help!?

Question

I am stuck on this one problem and I have managed to create a graph. My problem is creating a table of values. Your help is much appreciated with a 5 star guaranteed feedback. The link below has the image of the problem with the graph. All I need is a table of values.

Answer 1

Given your picture, I picked -1 to 5 for x values. Then I calculated the function (y) value for each x value. Enjoy!

x-val, y-val

-1, -7
0, -3
1, -1
2, -1
3, -3
4, -7

Answer 2

To create a table of values, pick an "x" and solve the equation (or go to it on the graph) and determine y.

You can pick obvious "x" values, like increments of .25: .25, .5, .75, etc... Or you could do .10, .20, .30.. Be sure to include some negative values too..

That's it.

Note: You could also pick y-values and determine x-values.

Answer 3

To get a table of values you just have to substitute values for x into the equation.
For example if x=-1
-(-1)^2+3(-1)-3=-1-3-3=-7
If x=+1
-(1)^2+3(1)-3=-1

Answer 4

start putting value of x and you'll get value of y. The graph is given so what did you manage to do?

Answer 5

perhap you can sub x=0 to find value y...

like that...>>

y= -x^2 +3x + 3
sub x =0

y= -(0)^2 +3x(0)+ 3
=3

continue subsituting x value till u are happy with the result.. maybe make it a five data point table??

so sub x,
=0
=1
=2
=3
=4



OK?

Answer 6

Plug the equation into excel.

Make a column of x values and then copy and paste the equation '=-a1^2+3a1-3' into the column for the y's.

Answer 7

Yup, best way is to put in values of x (I used to use 1 unit intervals, so x = 1,2,3,4,5, etc) and see what values of y you get.

Answer 8

haha i hv the same ques....
