Function: f(x) = x² -2x
Find y intercept:
y = 0² - 2(0)
y = 0
coordinates: (0, 0)
Vertex:
<u>-b/2a</u> = -(-2)/2(1) = 1
y coordinates = 1² - 2(1) = -1
vertex coordinates: (1, -1)
x intercept:
x² -2x = 0
x(x - 2) = 0
x = 0, 2
coordinates: (0, 0), (2, 0)
True statements:
option D
I would say so, yes this relation is a function because if graphed it passes the vertical line test.
The area of a circle is given in terms of circumference by
.. A = C²/(4π)
Then the ratio A/C is
.. A/C = C/(4π)
Substituting the given information, we have
.. 16 cm = C/(4π)
.. C = (4π)*16 cm = 64π cm
.. C ≈ 200.96 cm
