thats not a qustion im sorry i cannot answer it
Step-by-step explanation:
Answer:
first option
Step-by-step explanation:
Given
f(x) =
← factorise the numerator
=
← cancel (x + 4) on numerator/ denominator
= 2x - 3
Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is
x = - 4
Substitute x = - 4 into the simplified f(x) for y- coordinate
f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11
The discontinuity occurs at (- 4, - 11 )
To obtain the zero let f(x) = 0, that is
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = 
There is a zero at (
, 0 )
Thus
discontinuity at (- 4, - 11 ), zero at (
, 0 )
Answer:
fx = x^4 - 7x^3 + 7x^2 + 21x - 30
the symbol ^ means the power of.
Answer:
$142
Step-by-step explanation:
E = 426
E=3R
426 = 3R
R = 142
Answer:
Step-by-step explanation:
You haven't attached any graphs but as there area 3 distinct roots the graph will have 2 loops.
Also the end behaviour will be rising from the left negative values of f(x) and at the right it will rise to positive f(x).
