Answer: 23
Step-by-step explanation: 18+5=23
23-5=18
R=23
If you look at the pattern it would be x times 3 plus four so your function is f(x)=3x+4
Answer:
No. The answer on the right is positive 16 while the answer on the left is negative 9. 16≠-9
Step-by-step explanation:
If the roots are r1,r2,r3, the facotred polynomail looksl ike this
f(x)=(x-r1)(x-r2)(x-r3)
given
roots 4,2i and -2i
f(x)=(x-4)(x-2i)(x-(-2i))
f(x)=(x-4)(x-2i)(x+2i)
expand
f(x)=x³-4x²+4x-16
