Answer:

3/4

Step-by-step explanation:

The rate of change is referring to the slope, which can be calculated by rise/run. There are two points we can use to find the slope: (0,3) an (4,6), but feel free to use any points on the graph that you want to. Between those two points, the function's y value ("rise") increases by 3, while the function's x-value ("run") increases by 4. Divide 3 (rise) by 4 (run) in order to calculate the rate of change.

XB is the angle bisector of ZAXC. MZAXB23А.BVхC с

neonofarm [45]

To obtain x, we can sum the angles < AQB and < BQC

=> 5X + 8X - 24

=> 13X -24

we are also told that that the sum of their angles is 80

13X - 24 = 80

13 X = 24 + 80

13X = 104

Divide both sides by 13

x = 104/13

x = 8

Function Notation

Step-by-step explanation:

Step 1: Define

f(x) = ∛(x - 4)

f(-121) is x = -121

f(31) is x = 31

Step 2: Evaluate

f(-121)

Substitute in x: f(-121) = ∛(-121 - 4)
[Radical] Subtract: f(-121) = ∛(-125)
[Radical] Evaluate: f(-121) = -5

f(31)

Substitute in x: f(31) = ∛(31 - 4)
[Radical] Subtract: f(31) = ∛27
[Radical] Evaluate: f(31) = 3
