Range is {-2}
Domain is (-infinity,infinity)
Start by finding the vertex, which is the point the parabola turns. The x value is -b/2a, which you have in your notes here. b = -8 and a = 2 and therefore the x value of the vertex is 2. Plug that in to find the y value, which is -2.
Start by plotting this point and the y intercept, which is 6. The parabola will be a U shape, which goes upwards starting at the vertex. If you draw that using the side with the y intercept, you can just mirror it on the other side of the vertex.
Radius of the circle = r = 6.4 cm
Length of the arc = s = 8 cm
Measure of angle formed by the arc = <span>θ = ?
The radius of the circle, arc length and the angle made by the arc at the center of the circle are related by the equation:
s = r</span><span>θ
From here we can find </span><span>θ by:
</span><span>θ = s/r
Using the values, we get:
</span><span>θ = 8/6.4
</span><span>
θ</span><span>= 1.25 radians
Thus the radian measure of the angle </span>θ made by the arc will be 1.25 radians
