Answer:
(fog)(-2)=-5
Step-by-step explanation:
Given
f(x)= -7x+2
and
g(x)= √(x+3)
For finding (fog)(-2), we have to find (fog)(x) first
In order to find (fog)(x) we will put the value of g(x) in f(x) in place of x.
(fog)(x)= -7g(x)+2
Putting the value of g(x)
(fog)(x)= -7√(x+3)+2
We have to find (fog)(-2), so we have to put at the place of x in the composition
(fog)(-2)= -7√(-2+3)+2
(fog)(-2)= -7√1+2
= -7(1)+2
= -7+2
=-5
So,
(fog)(-2)=-5

Answer:
C. 2 -2 -3
Step-by-step explanation:
this is a combination of indicated operations
the number on the left of the indicated operation is the original set
the number '1/4' next to R shows that you need to multiply certain numbers by 1/4
the subscript on the R's shows which row the multiplication needs to be done on...
in this case it is saying that 1/4
+
will become the new
so multiply 1/4 by a number in the row
and then add that to the corresponding number from
an example: (1/4 x 8) + 0 -------> 2
2 would be the new first number in the second row
