The domain of any function is the set of the values of x that will make the function correct. If we try to extend indefinitely the parabola with specified attributes above on the plane where it is drawn, the parabola will expand. This allows all the real numbers be the x-values. Thus, the answer is letter "C. All real numbers"
ABCD is a square . if the coordinates of three of its vertices are A(-1,2a), B(a,2a), C(a,0), find the coordinates of D. BC is obviously 2a (it's a vertical line) then AB must be 2a (notice AB is horizontal) so BC = AC because it is a square 2a = a+1 a=1
Vertical line is a way to determine whether a functin is a function or not.
Answer:
Mean: 21
Median: 23
Mode: 27
Step-by-step explanation:
order from least to greatest:
1, 15, 18, 22, 23, 25, 27, 27, 31
mean: add all the numbers and divide by 9 bc thats how many numbers there are so that means the answer is
21
Median: to find the median you order the numbers from least to greatest and find out the middle number so in that case the median is 23
Mode: to find the mode you look to see what number is repeated multiple times, so the mode is 27
