Answer:
The axis of symmetry for the function f(x) is x=-3.
Step-by-step explanation:
The vertex form of a quadratic function is
.... (1)
Where, (h,k) is vertex and x=h is the axis of symmetry.
The given function is
.... (2)
From (1) and (2), we get
The axis of symmetry is
Substitute h=-3 in the above equation.
Therefore the axis of symmetry for the function f(x) is x=-3.

Answer:
when y=1 then x=0.5
Step-by-step explanation:
The graph is provided.
The equation y=4x-1 can be graphed by first graphing the -1 which is the y-intercept in the y=mx+b form. 4=m that is our slope. you can find the lines second point by moving 4 up and 1 to the right. rise/run =4/1. So when you move 4 up and 1 right you get another point on the line (1,3).
You can find out x=0.5 when y=1 by just tracing your finger over the graph and the point when y equals 1 the line intercepts x=0.5. Another screenshot is given.
I hope this helps!
