Given that F(x ) = x 2 + 2, evaluate F(1) + F(5).
To evaluate F(1), we substitute x = 1 into the function F(x) = x^2 + 2:
F(1) = 1^2 + 2
F(1) = 1 + 2
F(1) = 3
To evaluate F(5), we substitute x = 5 into the function F(x) = x^2 + 2:
F(5) = 5^2 + 2
F(5) = 25 + 2
F(5) = 27
Therefore, F(1) + F(5) = 3 + 27 = 30.
To evaluate F(1) + F(5), we need to substitute the values 1 and 5 into the function F(x) = x^2 + 2.
Let's start with F(1):
F(1) = (1)^2 + 2
= 1 + 2
= 3
Next, let's calculate F(5):
F(5) = (5)^2 + 2
= 25 + 2
= 27
Now, we can find the sum by adding F(1) and F(5):
F(1) + F(5) = 3 + 27
= 30
Therefore, F(1) + F(5) is equal to 30.
To evaluate F(1) + F(5), we first need to calculate the values of F(1) and F(5) separately.
The given function F(x) = x^2 + 2 represents a mathematical expression where the input value x is squared and then 2 is added to the result.
For F(1):
Substitute x = 1 into the expression:
F(1) = 1^2 + 2 = 1 + 2 = 3
For F(5):
Substitute x = 5 into the expression:
F(5) = 5^2 + 2 = 25 + 2 = 27
Now that we have the values of F(1) and F(5), we can calculate their sum:
F(1) + F(5) = 3 + 27 = 30
Therefore, F(1) + F(5) equals 30.
