Paper 2 · Functions and Graphs

The graph y=f(x)y=f(x) has yy-intercept (0,16)(0,16). State the yy-intercept of y=f(x)6y=f(x)-6.

Model answer

(0,10)

Also accepted: 0,10, 10

Explanation: A vertical translation down 6 subtracts 6 from every yy-value, so the new yy-intercept is (0,166)=(0,10)(0,16-6)=(0,10).
