Answer:
Vertex Form: y= 2(x−1)^2−7
Step-by-step explanation:
I believe this is correct
Altogether there are 8 parts. Thus, the part that is yellow is 3/8, or 37.5%
Remember the equation for slope is y=mx+b {m=slope, and b=y-intercept.} {Slope= rise/run}
1.) y= 2x+0
2.) y= -3/4x+0.5
P.S.: hope I helped :)
The given function is greater than or equal to 0 for the interval given as follows:
{x | x ≤ -3 or -1 ≤ x ≤ 0 or x ≥ 2}.
<h3>When a function is positive and when it is negative?</h3>
- A function is positive when it is above the x-axis.
- A function is negative when it is below the x-axis.
For this problem, with a closed interval, we have that the function is above for:
x ≤ -3, -1 ≤ x ≤ 0, x ≥ 2.
Hence the interval notation is:
{x | x ≤ -3 or -1 ≤ x ≤ 0 or x ≥ 2}.

From sin(180-x) = sin(x)
sin(150) = sin(180-30) = sin(30)
sin(120) = sin(180-60) = sin(60)
from cos(360-x) = cos(x)
cos(300) = cos(360-60) = cos(60)
cos(210) = cos(360-150) = cos(150)
from cos(180-x) = -cos(x)
cos(210) = cos(150) = cos(180-30) = -cos(30)
