Xf(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? a. between 3.0 and 3.5 and between 4.0 and 4.5 b. between 3.5 and 4.0 and between 4.0 and 4.5 c. between 4.0 and 4.5 and between 4.5 and 5.0 d. between 3 .5 and 4.0 and between 4.0 and 4.5 e. between 3 .5 and 4.0 and between 5.0 and 5.5

A. between 3.0 and 3.5 and between 4.0 and 4.5

Step-by-step explanation:

The idea here is that if a function is continuous and you have points on opposite sides of the x-axis, then there must be a zero-crossing between those points. As the table and graph show, ...

... (3.0, 4.0) and (3.5, -0.2)

are points on opposite sides of the x-axis. So, there must be a zero crossing between x=3.0 and x=3.5.

Likewise, ...

... (4.0, -0.8) and (4.5, 0.1)

are points on opposite sides of the x-axis. So, there must be a zero-crossing between x=4.0 and x=4.5

The appropriate answer choice lists both of these possible zero crossings.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

depends on how many days you are talking about
