F(x)=1/2 x + 5
The function F(x) can be written as:
F(x) = (1/2)x + 5
To find the value of f(x), given the function f(x) = 1/2x + 5, you need to substitute the value of x into the function and simplify the expression.
1. Start with the given function: f(x) = 1/2x + 5.
2. Replace the x in the equation with the specific value you want to evaluate. Let's say x = 3.
3. Substitute x = 3 into the function: f(3) = 1/2(3) + 5.
4. Simplify the expression inside the parentheses: 1/2(3) = 3/2.
5. Replace the simplified expression into the equation: f(3) = 3/2 + 5.
6. Find the common denominator of 2 and 1: 1/2 + (5 × 2)/2 = 1/2 + 10/2 = 11/2.
7. Simplify the expression: 11/2 = 5.5.
Therefore, f(3) = 5.5.
