Answer:
- 3 and x² + 2x - 3
Step-by-step explanation:
(a)
To evaluate g(1) substitute x = 1 into g(x)
g(1) = 1² - 4 = 1 - 4 = - 3
(b)
Substitute x = x + 1 into g(x)
g(x + 1) = (x + 1)² - 4 ← expand parenthesis using FOI
= x² + 2x + 1 - 4 ← collect like terms
= x² + 2x - 3
To find a specified term in a geometric sequence, you can use the formula: an = a1r^(n-1), where a1 = first term, n = position number of given term, r = common ratio, and an = value of term in given position.
Since we're only given a4 and r, I'm assuming a1 would be 1 since that would correspond to the rate (If we start off with one, a2 would be 1 * 2 = 2, a3 would be 2 * 2 = 4, and a4 would be 4 * 2 = 8). So now just plug in the numbers for the variables and solve.
a13 = 1(2)^(13-1)
a13 = 1(2)^(12)
a13 = 1(4096)
a13 = 4096
The 13th term of this geometric sequence would be 4096. I hope this answers your question.
