(fog)(x) and (gof)(x) f(x)= 8/1-5x g(x)= 1/x Then find the domain for each
1 answer:
To find FoG ( or F of G) you put the equation of G in for the X of F
FoG =
The domain is All Except 5 since it makes the bottom 0
GoF =
The domain is -Infinity to Infinity
FoG --- The picture --- You want the denominator the same for both of the numbers. By turning 1 into 1x/x it still stays 1 because the x's cancel out, but it can group with the 5.
Next you can multiply both sides (top and bottom) by x and get the final product.
GoF --- Multiply both sides by 5x+1 and get the final product
FoG =

Answer:
, all integers where n≥1
Step-by-step explanation:
we know that
The explicit equation for an arithmetic sequence is equal to
a_n is the th term
a_1 is the first term
d is the common difference
n is the number of terms
we have
Remember that
In an Arithmetic Sequence the difference between one term and the next is a constant, and this constant is called the common difference.
To find out the common difference subtract the first term from the second term
substitute the given values in the formula
The domain is all integers for
