Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
f(x) = x - 2
g(x) = x²
In order to find (fog)(-1) we must first find (fog)(x)
To find (fog)(x) substitute the g(x) into f(x) that's for every x in f (x) replace it with
g (x).
That's
(fog)(x) = x² - 2
To find (fog)(-1) substitute the value of x that's - 1 into (fog)(x)
We have
(fog)(-1) = (-1)² - 2 = 1 - 2 = - 1
Hope this helps you

Answer:
No
Step-by-step explanation:
For something to be a function, there must be no duplicate x values, or if there is they must represent the same y. The table has a duplicate value of 2 so it is not a function.
I hope this helps!
A negative number divided by a positive number yeilds a negative result
the rule is
if you divide or multiply 2 numbers with different sign (positive or negative), the result is negative
if you divide or multiply 2 numbers with the same sign (+ + or - - ), the result is positive
-42/8=-1 times 42/8=-1 times 21/4=--1 times 5 and 1/4=-5 and 1/4
The correct answer would be b 56
