Question

Consider the function f(x)=−2/3x+5 What is f(1/2)

Answer 1

`f(1/2)= (2)/(3) . (1)/(2) +5\\f(1/2)=(1)/(3) + 5\\f(1/2)= 5.33`

f(1/2) represents the function f evaluated at x=1/2, which is the value that the function would take if the variable x= 1/2.

Explanation:

• Replace the proposed value of x into the equation.
• In this case, x=1/2.
• Evaluate the result.
• Your result is the value that the function will take if the independent variable takes an specific value (in this case the independent variable is x, and you have to analize what happens if x takes the value of 1/2)
