Graph C. The equation of the line is y=2x+5. 5 is the y-intercept so the line has to go through that point.
Answer:
B) A random sample may represent the population <em>is your best answer.</em>
Step-by-step explanation:
Note that the answer choice says "may", which means that it doesn't <em>always</em> represent the population. Random samples means that they ask random people, and do not have a certain rule that they have to follow (such as recipients can only be a certain race, age, etc.) and that they can ask anybody they meet. This can give not only a higher chance of a general population's opinion, but also makes sure that there is not a high chance of obtaining misleading information.
For example, a random survey would not take place at a rally, in which most of the people would believe the same thing, and would answer fairly the same for the survey. Instead, a random survey may be taken at a busy intersection during the time when most people are out. You must note that though it has the best chance of getting a <em>more accurate</em> representation, it still isn't the most accurate. For the best accuracy, <em>everyone would have to answer the survey in which the survey question would affect</em>.

Answer:
2x(x - 4)
Step-by-step explanation:
ANSWER
y=x
y=x³
EXPLANATION
A function, f(x) has an inverse if and only if
Thus, the function is one to one.
For y=x or
Hence this function has an inverse.
For the function y=x² or f(x)=x².
This function has no inverse on the entire real numbers.
For the function y=x³ or f(x)=x³
This function also has an inverse.
For y=x⁴ or f(x) =x⁴
This function has no inverse over the entire real numbers.
