Question

x f(x)
3.0 4.0
3.5 -0.2
4.0 -0.8
4.5 0.1
5.0 0.6
5.5 0.7

For the given table of values for a polynomial function, where must the zeros of the function lie?

Answer 1

The zeros of the function are where the graph crosses the x axis. here it crosses the x axis between the first two points and the third and fourth points. Do you have to know exact coordinates of y when x = 0?

Answer 2

Because without a function to plug in 0 for x, there's no way to find out exactly what the y value is when x is 0. That's the best I have to give you. If you need clarification understanding it let me know.

Answer 3

i have the answer choices. ill put them below.

Answer 4

Oh, ok! Very good!

Answer 5

between 3 .5 and 4.0 and between 5.0 and 5.5

Answer 6

It's the first one. I drew the graph and here's what I got:
