Answer:
x = 1
Step-by-step explanation:
The line of symmetry is defined as the x value of the vertex of a parabola.
To find the vertex of a parabola, we need to convert to vertex form.
Vertex form looks like this:
, where -h is the x value of the vertex and k is the y value of the vertex.
H is also defined as 
where a is the coefficient of x squared and b is the coefficient of the x term.
The coefficient of the x squared term is 1 and the coefficient of b is -2.
Plugging in, we get 
, which is equal to 1. This can then be plugged into the equation as
, but k doesn't matter because all we need is the x-term. Now, our x-term is negative h, which is negative negative one, which is positive one. Therefore, our answer is x = 1.
Answer:
y=4
Step-by-step explanation:
Go to your graph , and make a straight line . A linear function is basically a line , so make a line to those numbers in the graph .
Answer:
Step-by-step explanation:
Rewrite equation: 
Factor out 
:
Divide both sides by 
:
Anything to the power of 1 is itself. Hence,
actually none of them since 212 is the biggest number and should be at the end but none of the answers say so
