Answer: The graph becomes narrower
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- |a| represents the vertical stretch if |a| > 1, vertical shrink if |a| < 1
- (h. k) represents the vertex
A vertical stretch means the curve gets narrower.
A vertical shrink/compression means the curve gets wider.
The mean would be 5
Reason for this is that the mean is when all data is summed up then divided by how many data points there are
So 4+4+7=15
Then divide by 3 would equal 5
I hope this helps!
Answer:
y intercept= 0
Step-by-step explanation:
in the formula y=mx+b, m is the slope and b is the y intercept. here we are not given "b" so the y intercept it 0
Step-by-step explanation:
7 (-12) = -84
it's literally -84
Solve for a by simplifying both sides of the equation, then isolating the variable.
a = 1
