(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

Answer:
1.18b
Step-by-step explanation:
Jacob had lunch at a restaurant and his bill was b.
Now, Jacob leaves 18% of his bill amount as a tip.
So, the tip amount at the rate of 18% of the bill amount will be
Therefore, the total cost of Jacob for the lunch will be b + 0.18b = 1.18b. (Answer)
