Answer:
Step 4 or the final bubble
Step-by-step explanation:
she did not subtract, she added
SO it should be x = -2
Start with
![f(x)=2x](https://tex.z-dn.net/?f=f%28x%29%3D2x)
Reflecting across the y axis means to swap x with -x, so you have
![f(x)=2(-x)=-2x](https://tex.z-dn.net/?f=f%28x%29%3D2%28-x%29%3D-2x)
Translating up 5 units means to add 5 to the function, so you have
![f(x)=-2x+5](https://tex.z-dn.net/?f=f%28x%29%3D-2x%2B5)
Answer:
Correct answer is: A = 8 m π
Step-by-step explanation:
In fact, it is necessary to calculate the surface of the circular ring representing the circular window frame:
It's formula:
A = (R² - r²) π where R = m + 2 and r = m - 2
A = ((m + 2)² - (m - 2)²) π = (m + 2 + m - 2) (m + 2 - m +2) π = 2m · 4 π
A = 8 m π
God with you!!!
Answer:
f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)f(x) = x2 – p(x + 1) – c, then (α + 1)(β + 1)
Step-by-step explanation:
