Answer:
The first one is a function. The other two are not functions.
Step-by-step explanation:
To find this, you use the vertical line test. If the vertical line touches multiple points on the graphed line, it is not a function. If the vertical line only touches the graphed line at one point, it is a function.
Good Luck! I hope this helps!
Answer:
range
Step-by-step explanation:
Mean- add all the numbers up and divide by how many numbers you added
65/8 =8.125
Range- Find the largest number and subtract the smallest number from it
20-3 =17
Median- put the numbers in order from least to greatest and find the number/s in the middle
3,3,4,5,6,8,16,20- since there are an even amount of numbers add the two in the middle and divide by 2
5+6=11 11/2 = 5.5
Mode- the number that repeats the most
3 repeats the most
Answer:
sorry i dont know
Step-by-step explanation:
Answer:
The values of k are 2/3 and -1
Step-by-step explanation:
Product of zeros = αβ= constant / coefficient of x^2 = 4/k
Sum of zeros =α+β = - coefficient of x / coefficient of x^2= -4/k
Given
Consider a= α and b= β
can be written as 
if we add 
in the above equation.
Putting values of αβ and α+β
The values of k are 2/3 and -1
