Answer:
y = f(x) = 7.
The output for the equation is 7 when x=2.
Explanation:
First, let's transform y = 3x + 1 into a function (f(x)) form.
f(x) = 3x + 1
When the Input, or x, equals to 2, we have:
f(x) = 3x + 1
f(2) = 3(2) + 1
f(2) = 6 + 1
f(2) = 7.
Given that y = f(x),
The output for the equation is 7 when x=2.
