Answer:
ac=-3, BC=57 I hope it will help you please follow me
Option D:
; all real numbers.
Explanation:
Given that the functions are
and 
We need to determine the value of
and its domain.
<u>The value of </u>
<u>:</u>
The value of
can be determined by multiplying the two functions.
Thus, we have,




Thus, the value of
is 
<u>Domain:</u>
We need to determine the domain of the function
The domain of the function is the set of all independent x - values for which the function is real and well defined.
Thus, the function
has no undefined constraints, the function is well defined for all real numbers.
Hence, Option D is the correct answer.
Step-by-step explanation:
y-15=x^2+10x
y-15+25=x^2+10x+25
y+10=(x+5)^2
