If f(x) = 2x2 + 1 and g(x) = x2 - 7, find (f + g)(x).
1 answer:
Answer:
(f+g)(x) =
Step-by-step explanation:
First, lets understand what (f+g)(x) means.
(f+g)(x) is when you are taking the values in the function f(x) and adding it to the values in the function g(x).
So, this is what the equation looks like when you substitute the functions in to (f+g)(x):
(f+g)(x) =
Now, combine like terms and Simplify:
(f+g)(x) =
This is your final answer.

Solution : Parabola
Step-by-step explanation:
As you can see only one variable is square in this situation, so it can only be a parabola. We can prove that it is a parabola however by converting it into standard form (x - h)^2 + (y - k)^2.
Respectively it's properties would be as follows,
Step-by-step explanation:
In my picture I made 6 slices, with one slice twice as large as the others.
Pretend that we cut the sausage slice in half. Then there would be 7 slices total.
We want to find P(Not Sausage).
Well since we sliced the big slice in two, we have 7 slices total. There are 5 slices without sausage.
The probability of getting a slice without sausage would then be 5/7.
