Hello!

❖ Mean = 4.8 Median = 4.5
The mean is the average. To find the mean add up all the numbers and divide by the number of numbers:
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.8
To find the mean, keep crossing out numbers until you are left with one number (for an odd amount of numbers). When you have an even amount of numbers, keep crossing out until you are left with 2 numbers. Add those 2 numbers and then divide:
4 + 5 = 9
9 ÷ 2 = 4.5

Answer:
two quadratic functions combined by addition
a linear function and a quadratic function combined by addition
two linear functions combined by multiplication
Step-by-step explanation:
-3x² + 5
(-4x² + 4) + (x² + 1)
-3x² + 5
(-3x² - x) + (x + 5)
-3x² + 5
(sqrt(5) - sqrt(3)x)(sqrt(5) + sqrt(3)x)
