Answer:
Solution:
When X=2
f(2)=1/2
= 1/2
When X= 1
f^-1(1)= 2*1
=2
When X=2
f^-1(2)=2*2
= 4
Step-by-step explanation:
I don't know if these are correct and if that last question is f^-1(2) or not.
Answer:
9*9
Step-by-step explanation:
Expanded form is writing out the exponent with multiplication.
9^3/9^1=9^2, or 9*9
Answer:
Step-by-step explanation:
If the polynomial is a cubic (third-degree), then it is
f(x) = x³+4x²-27x+40
and the other root is 2+i.
However, if we need two additional roots, it implies that the polynomial is a quartic (fourth degree). In that case, we need additional information. Reread the original question and update post if necessary.
Answer:
b=1
Step-by-step explanation:
9 (b + 7)= 72
9b + 63= 72
9b=9
b=1
unless you want the value when you plug the b back in with out solving then its 9
