Answer:
f(x) is positive for all x > 10
Step-by-step explanation:
Given function:
<u>Asymptote</u>
Asymptote: a line which the curve gets infinitely close to, but never touches.
Factor the denominator of the function to find the vertical asymptotes:
Therefore:
The function is undefined when the denominator is equal to zero.
Therefore, there are vertical asymptotes at x = -3 and x = 10
and a horizontal asymptote at y = 0
f(x) is positive for (10, ∞)
f(x) is negative for (-3, 10)
f(x) is positive for (-∞, -3)
7 / (x-3) = 1
(x-3) ((7 / (x-3)) = 1 (x-3) multiply both sides by (x-3), (x-3) on the left is cancelled
7 = x-3
3+7 = x - 3 + 3 add both sides by 3, 3 on the right is cancelled
x = 11
