Question 9 of 25

How does the graph of g(x) = x - 3 compare with the graph of the parent
function, fx) = X?

Answer 1

Linear equations

• y=x
• y=x-3

So g(x) is translated 3 units down on comparing to f(x)

Answer 2

If f(x) = x and g(x) = x - 3

then g(x) = f(x) - 3

So g(x) is a translation of f(x) by 3 units down.
