Function Composition
WELCOME EVERYBODY! ^^ TODAY I'LL POST ABOUT FUNCTION COMPOSITION, HIGHSCHOOL GRADE. THIS MATERIAL IS SO CHALLENGING. BUT YOU CAN GET USED TO IT! ^^ The Basic Characteristic Of Function Compositions I. Composition Function is : ( f o g ) (x) = f( g(x) ) = f composition g for x Example ^^ : f(x) = 5x – 4 and g(x) = 2x + 8 ( f o g )? = f ( g(x) ) f( 2x + 8 ) -----> 5( 2x + 8 ) – 4 ---> 10x + 40 – 4 ----> 10x + 36 as you can see above ... Basically change the X value of F(x) into g(x) so become f ( g(x) ) = f( 2x + 8 ) and because the F (x) = 5 x – 4 logically F ( 2x + 8) = 5 ( 2x + 8) – 4 ^^ -----> 10x + 8 How about ( g o f )? Value still the same : f(x) = 5x – 4 and g(x) = 2x + 8 ( g o f ) = g( f(x) ) g( 5x -4 ) -...
How To Determine Circle Equations
II. LOOK FOR CIRCLE EQUATIONS ^^ Now the reverse, how to find the equation of the circle if known its center and radius. Determine the equation of the circle below : 1. Center (0,0) r = 3 2. Center (-3, -1) r = 6 3. Point (6, 8) i s on a Circle A the center is (0.0). The circle equations? Answer 1. For the center (0,0) The circle equation : x² + y² = r² o So, the equation circle = x² + y² = 3 2. For the center not (0,0) r The circle equation : (x-a)² + (y-b)² =r² o So, the equation circle = ( x-(-3) )² + ( y – (-8) )² = 6² o The equation circle = (x+3)² + (y+8)² = 6² 3. For the Center ( 0,0) and point ( 6.8) ...
Cara Menentukan Persamaan Lingkaran
Menentukan persamaan lingkaran jika diketahui pusat dan jari-jari. Tentukan persamaan lingkaran berikut : 1. Pusat (0,0) Jari-jari = 3 2. Pusat (-3, -1) Jari-jari = 6 3. Titik (6, 8 ) melewati lingkaran A yang pusatnya (0,0). Persamaan Lingkaran A?
To Know kinds of Circle Equations, Look For Center and Radius
THERE ARE 3 TYPES OF CIRCLE EQUATIONS: 1. The center (0,0) equation : x² + y² = r² 2. The center (a, b) equation 1 : (x-a)² + (y-b)² =r² 3. The center (a, b) equation 2 : x² + y² + Ax + By + C = 0 atau x² + y² - 2ax – 2by + a 2 + b 2 - r² = 0 Description : - a,b = center of circle - x,y = a point on the circle - ...
Mengetahui Jenis-jenis Persamaan Lingkaran, Mencari Pusat dan Jari - Jarinya
ADA 3 JENIS PERSAMAAN LINGKARAN : 1. Pusat (0,0) persamaan : x² + y² = r² 2. Pusat (a,b) persamaan 1 : (x-a)² + (y-b)² =r² 3. Pusat (a,b) persamaan 2 : x² + y² + Ax + By + C = 0 atau x² + y² - 2ax – 2by + a 2 + b 2 - r² = 0 Keterangan : - a,b = pusat lingkaran - x,y = suatu titik di lingkaran - r ...
