Answer:-1.
Step-by-step explanation: The given function is:
F(x) = 14 - 0.5
To find the value of f(30), we substitute 30 in place of x in the function:
F(30) = 14 - 0.5(30)
First, we perform the multiplication:
F(30) = 14 - 15
Next, we subtract 15 from 14:
F(30) = -1
Therefore, the value of f(30) is -1.
