Question

Let f(x) = x2 – 2x + 2 and g(x) = x – 3. Find f(x) • g(x)

Answer 1

Where are you confused on what to do?

Answer 2

i don't know how to do this

Answer 3

is anybody going to show me how to do this please

Answer 4

Let me write an example.
If f(x) = 7 and g(x)= 9, what is f(x) * g(x) ? Well that would be 7*9.

does that make sense?

Answer 5

\[(x ^{2}-2x+2)(x-3)\]
first multiply the first term on the left side to the first term on the left side
in here:
\[(x ^{2}) will be multiplied by (x)\]
and it will be equal to:
\[x ^{3}\]
wherein you will just add their exponents...
do you get that?

Answer 6

yes i do

Answer 7

next, you'll multiply the first term from the left side to the second term of the right side
therefore, in your given:
\[(x ^{2})(-3)\]
the answer will become \[-3x^{2}\]
and so on.....
then combine like terms
your answer should be
\[x ^{3}-5x ^{2}+8x-6\]

Answer 8

\[f(x)\cdot g(x)\]means we multiply the two expressions:agree so far?
