In this question, we are going to be performing operations with functions.
00:09
First, we want to add f plus g of x.
00:16
That will be x minus 1 plus 2x squared, or 2x squared plus x minus 1.
00:27
Then, f minus g of x, which would be f of x minus g of x.
00:37
No need to put it in standard form.
00:40
I don't know why i did that for the first one.
00:42
Have it.
00:44
Next, we're going to multiply finding the product of the two functions, which would be x minus 1 times 2x squared.
00:57
And finally, the quotient of the two functions, which is x minus 1 divided by 2x squared.
01:10
Then we evaluate.
01:14
F plus g evaluated at 3 is 2 times 3.
01:22
Is 2 times 3 ,000...
