Answer:
The 80th term is 482
Step-by-step explanation:
8,14,20,26
This is an arithmetic sequence
Find the common difference by taking the second term and subtracting the first term
14-8 = 6
We are adding 6 each time
The formula for an arithmetic sequence is
an =a1+d(n-1) where a1 is the first term, d is the common difference and n is the term we are looking for
a80 = 8+6(80-1)
= 8 + 6*79
= 8+474
= 482
The 80th term is 482
First lets find the range of -2 sqrt(x - 3) + 8
x cannot be < 3 or f(x) would not be real
when x = 3 f(x) = 8
and for all other values of x f(x) will tend to - infinity
range is [8, - infinity)
if we do same for the 4 choices we'll see that - sqrt(x - 3)+8 will have same range
