Answer:
Hard to say where is this from?
Step-by-step explanation:
Answer:
x=0
Step-by-step explanation:
The axis of symmetry: when the equation is
The given equation is:
To make the a and b values more easily identifiable, we can rewrite it like this:
Now, we can tell that a=1 and b=0. Plug these into the equation :
Therefore, the equation for the axis of symmetry for the parabola is x=0.
I hope this helps!
Consider all graphs:
1. This is the graph of parabola that represents quadratic function
2. This is the graph of hyperbola that represents function
3. This is the square root's graph that represents function
4. This is the graph of exponential function
Answer: correct choice is D.
3/5 of the total responses expected = 87...
3/5x = 87
x = 87 / (3/5)
x = 87 * 5/3
x = 435/3
x = 145 <=== what was expected
