A counter example would be the number 2.
2 is a prime number, because it only has two factors ( itself and 1)
Yet 2 is also an even number, because it can be exactly divided by two.
So the number 2 proves that not every prime number is odd.
Answer:
Step-by-step explanation:
We'll write the polynomial using only the roots required to simplify calculations. However, it states the final answer should not have a radical or complex number in. Therefore, we need to rid them:
Expanding this, we get:
.
Answer:
21
Step-by-step explanation:
Start with the inside first.
The inside is g(3).
g(3) can be found by using function, g.
g(x)=3x-4 so g(3)=3(3)-4=9-4=5.
So now we have that:
f(g(3))
f(5)
We can find f(5) by replacing x in the expression x^2-2x+6 with 5:
(5)^2-2(5)+6
25-10+6
15+6
21
This means f(g(3))=f(5)=21
