Answer:
f(1) = 81
Step-by-step explanation:
given is f(n + 1) = 1/3f(n)
f(3) = 9
ayou need to find f(0) before you can answer what is f(1).
Just start by applying for...
n=0
f(0+1) = 1/3 * f(0)
f(1) = 1/3 * f(0)
n=1
f(1+1) = 1/3 * 1/3*f(0)
f(2) = 1/9 * f(0)
n=2
f(2+1) = 1/3 * 1/9* f(0)
f(3) = 1/27 * f(0)
But it is given that f(3) = 9 so substitute this in the line above to calculate the value of f(0)....
9 = 1/27 * f(0)
Multiply left and right of the = sing by 27 gives
f(0) = 27 * 9
f(0) = 243
We already know this next line because we started with n=0
f(1) = 1/3 * f(0)
Substitute f(0) = 243 in the line above to finally calculate the value of f(1).
f(1) = 1/3 * 243
f(1) = 81
Answer:
Y = 4 and X = -6 , So the equation would be 4 + -6
Step-by-step explanation:
Look at were the line go across the numbers in Line Y and Line X this will help you understand more. And i also answered first :)
Answer:
( -2,-2 )
Step-by-step explanation:
when you reflect something on the x-axis, you make the x coordinate stay the same and you change the y coordinate. so in this case, the -2 would stay the same and the 2 would become the opposite of that number and become -2. hope this helps.
