Graph the function y = 4x4 – 8x2 + 4. Which lists all of the turning points of the graph?
1 answer:
A function assigns the values. The correct option is C.
<h3>What is a Function?</h3>A function assigns the value of each element of one set to the other specific element of another set.
If we plot the function, y = 4x⁴ - 8x² + 4, then it can be observed that the lists all of the turning points of the graphs are (–1, 0), (0, 4), and (1, 0).
Hence, the correct option is C.

Answer:
There is no enough evidence to support the claim that the proportion of US teens that have some level of hearing loss differs from 20%.
P-value=0.12
Step-by-step explanation:
We have to perform a test of hypothesis on the proportion.
The claim is that the proportion of US teens that have some level of hearing loss differs from 20%.
Then, the null and alternative hypothesis are:
The significance level is assumed to be 0.05.
The sample, of size n=1981, has 369 positive cases. Then, the proportion is:
The standard error of the proportion is:
Now, we can calculate the statistic z:
The P-value for this two-tailed test is:
The P-value is below the significance level, so the effect is not significant. The null hypothesis failed to be rejected.
There is no enough evidence to support the claim that the proportion of US teens that have some level of hearing loss differs from 20%.
