Find the y-intercept of the graph of f(x)+3.

[1]
a.i.

Find the y-intercept of the graph of f(4x).

[2]

Markscheme

y-intercept is 11   (accept (0, 11) )     A1 N1 

[1 mark]

a.i.

valid approach        (M1)

eg  f(4×0)=f(0),   recognizing stretch of 14 in x-direction

y-intercept is 8      (accept (0, 8) )    A1 N2 

[2 marks]

a.ii.

x-intercept is 52(=2.5)   (accept (52,0) or (2.5, 0) )    A2 N2 

[2 marks]

b.

correct name, correct magnitude and direction        A1A1 N2

eg   name: translation, (horizontal) shift (do not accept move)

eg   magnitude and direction: 1 unit to the left, (10), horizontal by –1
