f(x) + c -> up by c
f(x) - c -> down by c
f(x + c) -> left by c
f(x - c) -> right by c
For y = f(x + c), the y value of x now takes the y value of the function of x + c, or the one c to the right of x, shifting the entire graph left by c.
Answer: The operation is “division” and the answer is “13 pens in each”.
Explanation: 52 divided by 4 = 13
$14.95+15%=$17.19 so the tip is $2.24
Answer:
y = 2.3x is a linear function.
Step-by-step explanation:
A linear function is a function with all of its terms to the first degree, in other words, none of its terms has an exponent. This means that when the function is plotted out, the resulting graph will be a line. The function, ( y = 2.3x) satisfies both of these requirements, hence it is linear.
Answer:
"Members of a population are organized in clusters, each of which is representative of the population, and then whole clusters are randomly selected to make up the sample"
Step-by-step explanation:
In cluster random sampling, "the population is divided, usually geographically, into groups that generally have the same size. A certain number of groups are randomly chosen, and every individual in the chosen groups are chosen for the sample."
In accord with this logic, the second choice, "Members of a population are organized in clusters, each of which is representative of the population, and then whole clusters are randomly selected to make up the sample" seems to be correct.
NOTE: This may not be the correct answer. I am simply basing my answer on the definition I have learnt.
