Q. Use the following function rule to find f(3).f(x)=7−x75f(3)=□
Identify Function and Value: Identify the function and the value to substitute.We are given the function f(x)=7−x75 and we need to find f(3). This means we will substitute x with 3 in the function.
Substitute x with 3: Substitute x with 3 in the function.f(3)=7−(375)Now we will perform the division within the parentheses.
Perform Division: Perform the division.75 divided by 3 is 25.f(3)=7−25Now we will subtract 25 from 7.
Subtract 25 from 7: Subtract 25 from 7. f(3)=7−25f(3)=−18We have found the value of f(3).
