the point that the function intercepts the x axis are the zeros of the function, where the products set equal to zero give you the x coordinate in which it intercepts.
x=-15 and x=9
set both equal to 0
x+15 and x-9
These are your two products
(x+15)(x-9)
or
x^2+6x-135
Answer:
Step-by-step explanation:
9x1
You would add 2+7 which =9 then x+1 that’s 1 so it would be 9x1
Answer: Choice [D] - "power of a power" ✅
Step-by-step explanation:
Hii, do you need to know which law you should use to simplify
?
No problem!
The law we will use here is "power of a power".
What "power of powers" means is we raise a power to a power, which is exactly what we do here: We raise x^4 to the power of 9. To simplify our expression, we multiply the powers. (
)
So the right answer is: Choice [D] - "Power of a power"
The simplified answer is 
Voila! There's our answer, cheers!
