Answer:
\(f(3)=8\)
Step-by-step explanation:
Given: The function \(f(x)=5x-7\)
To find: The value of the given function at x=3
Solution:
The given function is:
\(f(x)=5x-7\)
Now, substituting the value of x in the above given function, we get
\(f(3)=5(3)-7\)
Upon solving the above equation, we get
\(f(3)=15-7\)
\(f(3)=8\)
Therefore, the value of the given function at x=3 is 8.
