Question

If f(x) = 5 + 8, what is f(x) when x is 10?
a) 4
b) 9
c) 13
d) 36

Answer 1

The function f(x) = 5 + 8 will always have a value of 13, regardless of the value of x. Therefore, f(10) equals 13.

Step-by-step explanation:

The function f(x) = 5 + 8 is constant and does not depend on the value of x. This means that for f(x) when x is 10 or any other number, the function's value will always be the sum of 5 and 8. So, the value of f(10) is 5 + 8 = 13, making the correct answer option c) 13.
