Answer:
Average rate of change of function is -2.
Step-by-step explanation:
Given
.
we have to find the average rate of change for the quadratic function from x=−2 to x = 2.
![f(-2)=\frac{-1}{4}(-2+4)^2-8=\frac{-1}{4}(4)-8=-9](https://tex.z-dn.net/?f=f%28-2%29%3D%5Cfrac%7B-1%7D%7B4%7D%28-2%2B4%29%5E2-8%3D%5Cfrac%7B-1%7D%7B4%7D%284%29-8%3D-9)
The average rate of change of the function f(x) on interval [-2,2] is
![\frac{f(b)-f(a)}{b-a}=\frac{f(2)-f(-2)}{2-(-2)}=\frac{-17-(-9)}{4}=\frac{-8}{4}=-2](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%3D%5Cfrac%7Bf%282%29-f%28-2%29%7D%7B2-%28-2%29%7D%3D%5Cfrac%7B-17-%28-9%29%7D%7B4%7D%3D%5Cfrac%7B-8%7D%7B4%7D%3D-2)
Answer:
7
Step-by-step explanation:
→ Find the scale factor
30 ÷ 25 = 1.2
→ Multiply answer by 20
20 × 1.2 = 24
→ Equate equation to 24
4x - 4 = 24
→ Add 4 to both sides
4x = 28
→ Divide both sides by 4
x = 7
Is this all the problem wants ?
