Answer:
vertex = (- 1, 1 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = -
y = x² + 2x + 2 ← is in standard form
with a = 1 and b = 2 , then
x = - = - 1
substitute x = - 1 into the equation for y- coordinate of vertex
y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1
vertex = (- 1, 1 )
Answer:
Look below.
Step-by-step explanation:
For one, g+g+g+g does not equal g^4. That equals g·g·g·g.
But like you said, 4g = g·g·g·g as well, so shouldn't they be equal?
The answer is more simple than you might expect:
We'll do the second one first. I don't know why, that is just how it is going to be done.
Let's assign a value to 'g'. We'll call it g = 3.
3 to the 4th power is
1) 3·3 = 9
2) 9·3 = 27
3) 27·3 = 81.
So = 81.
But, you probably figured out, with g = 3, that 4g = 12, since 3·4 = 12.
Obviously, 81 ≠ 27, meaning these are not the same, and that is the main difference.
