What is the equation for a geometric sequence with a first term of 4 and a second term of −8?
1 answer:
<h3>
Answer:</h3>
<h3>
Step-by-step explanation:</h3>
The common ratio is -8/4 = -2. The general formula for the n-th term is ...
... an = a1·r^(n-1) . . . . . . note the use of the caret (^) and parentheses
For r = -2 and a1 = 4, this becomes ...
... an = 4·(-2)^(n-1) . . . . approximately matches the 2nd selection

When simplifying x3. X2, the exponents are added together true of false
Your answer is true
Domain = all possible x values
You can see it starts from -5 and it goes till 4. Therefore domain -5 < x < 4
Solution: [-5,4]
