<span>g(x) = x3
– x2 – 4x + 4 </span>
<span>You can find
the zeroes by factoring the equation. x<span>2 </span>(x - 1) - 4(x - 1) = 0 </span>
<span>(x2
- 4) (x - 1) = 0 </span>
(x + 2) (x -
2) (x - 1) = 0
x = 2, -2,
and 1
The
following are the key features of g(x):
g'(x) yields
the slope
g''(x) yields
the concavity
g'(x) = 0 provides
the critical points
<span>g''(x) = 0 provides the point of inflection</span>
Answer:
y= 3x+4
Step-by-step explanation:
2y-6x=8
add 6x to each side
2y-6x+6x=6x+8
2y= 6x+8
divide each side by 2
2y/2 = 6x/2 + 8/2
y= 3x+4
Answer:
Step-by-step explanation:
You know that anything to the zeroeth power is 1, so the equation is now
-7 * 1, or -7.
The equation of a circle is written as ( x-h)^2 + (y-k)^2 = r^2
h and k is the center point of the circle and r is the radius.
In the given equation (x+3)^2 + (y-1)^2 = 81
h = -3
k = 1
r^2 = 81
Take the square root of both sides:
r = 9
The center is (-3,1) and the radius is 9
