The equation of f(x) is f(x) = x + 4
<h3>How to determine the equation?</h3>
The given parameters are
f(-1) = 3 and f(1) = 5
Start by calculating the slope (m) using:

This gives

Evaluate
m = 1
The equation is then calculated as;
f(x) = m(x - x1) + f(-1)
This gives
f(x) = 1(x + 1) + 3
Expand
f(x) = x + 4
Hence, the equation of f(x) is f(x) = x + 4
