Answer:
Equation of the axis of symmetry is: x = 3
Step-by-step explanation:
The equation
is the equation of a parabola, of the form
whose vertex is located at the x-coordinate:
Then, for our case the x position of the given parabola, is:
Then the equation of the axis of symmetry, which is a vertical line that goes through the vertex, would be given by:
x = 3
Answer:
the third one and the last one is correct
Step-by-step explanation:
we already know the second one is wrong because of it's set up.
just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)
Answer:
29
Step-by-step explanation:
Answer:
The equation of line can be written as,
y = mx + c
where, m is slope
and c is intercept of line.
Now, Suppose we have equation: ax + by + c = 0
So, transforming the given equation in above standard equation.
⇒ by = -ax - c
⇒ 
Now comparing this equation with standard equation. We get,
and 
Hence, Intercept = 
for line ax + by + c = 0.
Answer:
Step-by-step explanation:
y=x²+4x+4
or y=(x+2)²
or y=(x+2)²+0
vertex Is (-2,0)
