Answer:
The corresponding point is <em>(-8, -6).</em>
Step-by-step explanation:
Given that
(-6,-6) lies on the graph of
A function is represented in the form:
i.e. (-6,-6) means value of x = -6 is put and value y came out as -6.
Now, we have to find the corresponding point on .
We know the value of
Let us find the value of x where becomes equal to -6
So, let us put value of in
:
(as per given statement)
So, the corresponding point is <em>(-8, -6).</em>
A graph shows the function can be factored as
f(x) = (x -1)((x-8)² +1)
There is one real root and there are two complex roots. The latter can be found from the vertex form factor:
(x - 8)² + 1 = 0
(x - 8)² = -1
x - 8 = ±√(-1) = ±i
x = 8 ± i
The zeros of the function are {1, 8-i, 8+i}.
f(x) = (x -1)((x-8)² +1)
There is one real root and there are two complex roots. The latter can be found from the vertex form factor:
(x - 8)² + 1 = 0
(x - 8)² = -1
x - 8 = ±√(-1) = ±i
x = 8 ± i
The zeros of the function are {1, 8-i, 8+i}.
