Answer:
The last option is correct. (f*g)(x) = x² - 5
Step-by-step explanation:
Since is f * g you have to multiply them together.
x² - 2 * x - 3 (x)
Next ust simplify.
x² -5x
Answer:
we can do it by simplifying 8 to
to make both powers base two, and subtracting the exponents.
Step-by-step explanation:
We have been given the expression 
8 can be rewritten as 
Hence, the given expression becomes

After subtracting the exponents on left hand side of the equation we get:

we can do it by simplifying 8 to
to make both powers base two, and subtracting the exponents.
Answer:
the second one
slope is negative go down one right 2
It can not be simplified because the numerator and denominator can not be divided between the same number, so that each results an integer number.
