Answer:
Step-by-step explanation:
the lines weren't really clear so sorry if its a bit messy
Given that the sequence is:
1,2,4,8,32
the recursive formula will be found as follows:
first term is=1
the sequence can be written as:
1,2,4,8,32
=(1*2^0),(1*2^1),(1*2^2),(1*2^3),(1*2^4)
thus the recursive formula will be
an=a1(r)^(n-1)
plugging the values we get:
an=1(2)^(n-1)
Parallel = has same slope
On points( 3,4) (-2,2)
(2-4)/(-2-3) = -2/-5 = 2/5 slope
Use same formula: (y2-y1)/(x2-x1)
Find the slope of the other points:
(-2,-5) and (-7,-3)
(-3-(-5))/(-7-(-2)) = 2/-5 = -2/5
(-1, 1) and (-6, -1)
(-1-1)/(-6-(-1)) = -2/-5 = 2/5
(0,0) and (2,5)
(5-0)/(2-0) = 5/2
(1,0) and (6,2)
(2-0)/(6-1) = 2/5
(3,0) and (8,2)
(2-0)/(8-3) = 2/5
Which has same slope of 2/5?
You can see :)
Answer:
B. F(x) = 0.4x² - 1
Step-by-step explanation:
→The function F(x) has shifted downwards, meaning there has to be a 1 being subtracted.
→The function F(x) has grown wider, meaning there has to be a number of absolute value less than 1.
<u>This means answer choice, "B," is correct.</u>
