Question

For the given table of values for a polynomial function, where must the zeros of the function lie?
x
2.0
2.5
3.0
3.5
4.0
4.5

f(x)
2.8
1.1
-0.8
-1.2
-0.3
0.7
A. between 2.0 and 2.5 and between 4.0 and 4.5
B. between 2.5 and 3.0 and between 4.0 and 4.5
C. between 2.0 and 2.5 and between 3.5 and 4.0
D. between 2.5 and 3.0 and between 3.5 and 4.0

Help please !!!

Answer 1

@Vocaloid help please thank you !! :)

Answer 2

i'll pose this to you

Answer 3

for this example the zero's lie on the black does, or where the graph intersects the x-axis i.e when f(x)=0 or y=0

Answer 4

dots*

Answer 5

so in this question , we need to find the position of points where 0 lies in

Answer 6

so find possible y values where zero lies between them

Answer 7

for corresponding x values

Answer 8

how I can graph that function in my calculater and get the zeros of this function? @chris00

Answer 9

you don't need to graph it, we can just visually look at it. perhaps we shall write these values in a table.
