Answer:
Vertex = (-1, 0)
The axis of symmetry is x = -1
Minimum point is (-1, 0)
Range is y ≥ 0
In the interval notation [0, ∞)
Step-by-step explanation:
The given function is y = x^2 +2x + 1.
Write the given equation in the form of y = (x -h)^2 + k.
Here (h,k) is the vertex.
y = x^2 + 2x + 1
y = (x + 1)^2
Vertex = (-1, 0)
Axis of symmetry
The axis of symmetry splits the parabola in 2 equal parts.
In this equation, the axis of symmetry is x = -1
Maximum/minimum value
The parabola goes maximum when there is negative sign, it goes minimum when there is positive sign.
Here we have positive sign in front of (x + 1)^2, therefore, it is minimum at
y= 0
When y =0, x = -1
Therefore, minimum point is (-1, 0)
Range
Y- axis represents the range.
Here the minimum is 0, the maximum goes upto infinity.
Range is y ≥ 0
In the interval notation [0, ∞)
Herewith I have attached the graph of the function.
x-3y=-9 ???
Use this fact to show that 0.077777...=7/90
Step-by-step explanation:
Here we have , 0.7777…=7/9 . And using this fact we need to find show that
0.077777...=7/90 . Let's show this:
In the equation , Let's evaluate RHS :
⇒
⇒
But According to question , 0.7777…=7/9 , So
⇒
⇒
⇒
⇒
Since , RHS=LHS . Therefore, is proved using fact 0.7777…=7/9 .
Which description best describes the solution to the system of equations?
line y=-x+2 intersects line y=3x+1.
Lines y=-x+2 and y = 3x + 1 intersect the x axis
lines y=-x+2 and y 3x+ 1 intersect the y-axis
Line y=-x+2 intersects the origin
this is right ↑ I took the test myself and was a little unsure bc some people were saying it was 'lines y=-x+2 and y=3x+1 intersect the y-axis' but it is actually A! Thanks so much! Have a great day!
