Given f(x) = x² - 10x + 22, what is the range of f?
adoni [48]

Answer:

[-3, ∞)

Step-by-step explanation:

There are many ways to find the range but I will use the method I find the easiest.

First, find the derivative of the function.

f(x) = x² - 10x + 22

f'(x) = 2x - 10

Once you find the derivative, set the derivative equal to 0.

2x - 10 = 0

Solve for x.

2x = 10

x = 5

Great, you have the x value but we need the y value. To find it, plug the x value of 5 back into the original equation.

f(x) = x² - 10x + 22

f(5) = 5² - 10(5) + 22

      = 25 - 50 +22

      = -3

Since the function is that of a parabola, the value of x is the vertex and the y values continue going up to ∞.

This means the range is : [-3, ∞)

Another easy way is just graphing the function and then looking at the range. (I attached a graph of the function below).

Hope this helped!

HELP ME PLEASE ITS DUE TODAY!!!!
Stells [14]

Step-by-step explanation:

- 5 - ( - 4) =  - 5 + 4 =  - 1 \\  - 4 - ( - 5) =  - 4 + 5 = 1 \\  - 4 - (5) =  - 4 - 5 =  - 9 \\ 4 - ( - 5) = 4 + 5 = 9

Therefore ranking them from least to most:

- 4 - (5) \\  - 5 - ( - 4) \\  - 4 - ( - 5) \\ 4 - ( - 5)
