Question

if you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Answer 1

f(x) = x + 13

Explanation:

Given f(x) then f(x) + c represents a vertical translation

• If c > 0 then vertical shift up ↑ of c units

• If c < 0 then vertical shift down ↓ of c units

here c = + 13, hence

f(x) = x + 13
