TEST REVIEW
![Page 2: CHAPTER 1 TEST REVIEW. 1.Write the equation of the line perpendicular to the line 4x+y = 1 and runs through (2,-1) y + 1 = ¼(x-2) y = ¼x - 1½.](https://reader036.fdocuments.in/reader036/viewer/2022082820/56649f475503460f94c68ebe/html5/thumbnails/2.jpg)
1. Write the equation of the lineperpendicular to the line
4x+y = 1 and runs through (2,-1)
y + 1 = ¼(x-2)
y = ¼x - 1½
![Page 3: CHAPTER 1 TEST REVIEW. 1.Write the equation of the line perpendicular to the line 4x+y = 1 and runs through (2,-1) y + 1 = ¼(x-2) y = ¼x - 1½.](https://reader036.fdocuments.in/reader036/viewer/2022082820/56649f475503460f94c68ebe/html5/thumbnails/3.jpg)
Given f(x) = 6x-4 and g(x) = x2+2
2. Find f(g(-2) 3. Find g(f(x))
4. Find the inverse of f(x)
f(6) = 32
(6x-4)2 + 236x2 – 48x + 18
x = 6y – 4
x+4y-1 = 6

5. Find the center and radius: x2 + y2 + 2x - 14y = 71
x2 + 2x + 1 + y2 – 14y + 49=71 + 1+ 49 (x+1)2 + (y-7)2 = 71 + 1 + 49
(x+1)2 + (y-7)2 = 121
C(-1,7) r = 11
