We have a function f(x) defined below:
f(x) = (4x²-36x)/(x-9)
We can factor the top:
f(x) = (4x)(x-9)/(x-9)
We see an (x-9) term in the top and bottom. This means that we can reduce f(x) down to:
f(x) = 4x
But we must keep in mind that due to the canceling (x-9) terms, there is a <em>removable discontinuity (hole) at x = 9</em>
To find the zeros of f(x), simple set f(x) = 0 and solve for x:
f(x) = 4x
0 = 4x
x = 0
Choice B
Answer:
A. subtract s: -7, -10, -13
Step-by-step explanation:
Plug in -2 for x and evaluate.
<span>f(-2) = (-2)^4 + 3(-2)^3 - 6(-2)^2 + 3
f(-2) = 16 - 24 - 24 + 3
f(-2) = -29
-2 is not a zero of the polynomial.

Answer:
just a few feet (within 1 to 10)
Step-by-step explanation:
You cannot enter zero, since the city could be inundated with water, so include something between 1 or at most 10 feet.
No, the Pythgorean Theorem only applies to right triangles. To get two right triangles, you divide a rectangle diagonally. Dividing a hexagon into two pieces produces trapezoids or pentagons depending where it is divided.
