Answer:
g(1) = 1
Step-by-step explanation:
g(1) with x = 1 corresponds to x ≠ - 2, - 1 with g(x) = x³ - x² + 1 , then
g(1) = 1³ - 1² + 1 = 1 - 1 + 1 = 1
Answer:
T(n) = [n(n + 1)] ÷ 2
Step-by-step explanation:
Sequence = 1, 3, 6
First term = 1
Second term = first term + 2 = 3
Third term = second term + 3 = 6
From the sequence :
Each successive term is doubled together with an increment of '1', that is;
Term 'n' : n(n + 1)
Then, the total is divided by the term 'n'.
Therefore, the nth term is expressed as
T(n) = [n(n + 1)] ÷ 2
For instance,
n = 1
T(1) = [1(1 + 1)] ÷ 2
T(1) = 1
n = 3
T(3) = [3(3 + 1)] ÷ 2
T(3) = 12 ÷ 2 = 6

Step-by-step explanation:
3^2 + 3^2 =5^2
9 +9 =25
18 =25
False 18 is not equal to 25.
We know that this parabola intecepts the x-axis in 6 and -3. This means that is a vertical axis parabola. But also we know that our parabola passes through (1,10). Graphing these we conclude that is a concave down parabola
The general formula for this is:
To solve this we need to form a 3 equations system with our three points
We can solve for c in the first one
and replace in the second one and solve for b:
And replace c and b in the third equation:
Solve for a:
so b and c:
So:
